Sex Determination: More Complicated Than You Thought
HTML-код
- Опубликовано: 5 окт 2024
- From something as small and complex as a chromosome to something as seemingly simple as the weather, sex determination systems vary significantly across the animal kingdom. Biologist and teacher Aaron Reedy shows us the amazing differences between species when it comes to determination of gender.

My insights about this videos
-Male social insects are walking sperms
-Turtles have hot chic and cool dudes
-Desert lizards are Amazons
-Finding Nemo is a lie
-For an aquatic invertebrate, if you're on the top you are a male. If you are in the bottom, you're a female.
-If somebody ask the gender of your unborn kids, just say yes

So as global warming speed up, will all turtles be female?
Global warming would have to cause a much faster temperature shift to show any definitive shift balance of sexes for painted turtles. Not only that, turtles could use behavioral adaptation to choose underground nests that are much cooler to produce more males.
No
this came out in a test, where the question asked how global warming can affect the population of turtles

I don't think he covered the snails and slugs.
some mollusks are hermaphrodites
Chrice Chiu snails are trans ,they are both
Hermaphrodites are not trans

He also didn't cover the lizards very well. Based on this video alone, I'm not really sure how lizards can reproduce if they're always female.

@adarshyadav59😂😂32
and then how did lizards evolve and how they didnt got wipeed out by disease?
Natural evolution, if something change then gens do to.
Confy lizard I have heard about them and apparently they are traped on an island and there where males but the species almost went extinct and all that was left was female capable of cloning.
Cloning can be an imperfect process, which means mutations (some of which may be beneficial) can occur... but it is at a much slower rate than species who jumble their genes via sex. It is a risky strategy for a species to take, but it does allow for some degree of variation.
Short answer is it hasnt happened yet, but there's no guarantee it would ever happen either. Statistics mean they are more likely to not have genetic resistance in their population, not that they are more vulnerable. Clones are all the same, but not all diseases are deadly either. Kind of like how humans have almost no genetic resistance to HIV (a few might), but there are enough of us around that one Might mutate in some way that prevents infection or spread, or deadliness, or anything that could help. If we mutate, we can pass it on, and clones have to inherit it, but we can mix it up mutayions through chromosome crossover, but they go one mutation at a time.
How did amoebas evolve, how didn't they get wiped out...
Just like that...
I really like the clownfish system. We should all give it a try.
+Petit Orenji no
John Hasben
afraid?
Petit Orenji why would i be afraid? because some dude who could just be gay and there is nothing wrong with it turns into something his body is not? like think of it if no one is trans then the birth rate and the minds of men and female will be good cause they know hey the one i'm dating is me (I'm going with hedrosexual relationships ok) so a guy wants a kid with a person he been with for about 3 years and he wants a family with a born woman there won't be a problem but with a trans it's impossible and the three years he could been with a born woman he has wasted it on that person
I'm not saying that his mind might change but why should it. Cause some dude thought he could have did what a female can,no.
So no i'm not afraid saying someone is afraid is the lowest argument point you can make.
John Hasben
Lol. Too many run-on sentences, can't understand. Interestingly, run--on sentences make you sound very afraid.
if you want an offspring to carry on your name, you deal with that problem. Why get a woman involved? Typical egocentric male issues.
I don't know what hedrosexual is.
Petit Orenji hedrosexual is straight people. Also people use run on alot online when in the comment section if you cant read run on you can't read just look at all of the words but excuse me oh well and also why you think people in relationships have families most want them and to create that child you can;t say oh you do this on you look scared is invalid in this conversation also typical egocentric male issues in the end people want to have a family that means making children yes it's ok for homosexual people to raise a child ( for you because you don't know what hedrosexual means I think you don't know what homosexual is it means gay) also instead of you know trying you gave up and tried to go against me for my typing style now please try to counter my argument please

@@ok2713 it is done to prevent female foeticide.
@@vrindatheresa9645 foeticide ?
@@Cheezy_Bunz yes... Due to the patriarchal culture of India, some people valued their sons more than their daughters. Daughters were sometimes seen as burden as they had to be married off to other families with dowries. So, this preference lead to abortion of female child. Hence it is illegal to reveal the child's gender before birth... Hope this helped😁
So Nemo's father will be a female someday.

There are advantages and disadvantages. Obviously, they cannot evolve and adapt as quickly as sexually reproducing lizards, but they can quickly populate a new area with just one lizard. It's interesting to see how differently some lizards have evolved from others, and why they did so. Somewhere along the way, it worked out better for them.
That was more informative & comprehensive than all of the hours they taught us this in school combined :)
Of course, it's even more complicated than that. Not all species are sexually dimorphic. Certain lizards, as you pointed out, undergo parthenogenesis. If such a lizard were able to speak, the word "gender" would have no meaning to it. Certain fungi have thousands of genders. Gender is a somewhat arbitrary evolutionary construct: even among humans, and this is my main point, we have other - biologically verifiable - variants to the male-female system. A transgender person's brain anatomy, for example, is much closer to that of their (so-called) biological gender (i.e. a transgender female has brain chemistry much more similar to that of a "biological" female than she does to a male).
Also, the chance is not 50/50, especially at a zygotic level. Conception produces somewhere between 25-50% more male zygotes (some research indicates this may be the result of glucose levels in utero: see DOI: 10.1098/rspb.2004.2773). Male zygotes are more likely to fall prey to miscarriage and stillbirth, but at birth the ratio is still higher - roughly 106 boys for every 100 girls. Males are much more likely to fall prey to violence after birth, as well: think of the all-male drafts implemented in times of war or the "save the women and children first" mentality, which (I would hypothesize) has its groundings in strict evolutionary psychology. Environmental conditions also affect this: males are, biologically speaking, a riskier proposition because they have to compete for mating rights whereas females are all but guaranteed the chance at reproduction. Thus, in bad environmental conditions - i.e. not enough food (low glucose) and so on - the parents stand a greater chance at passing on their genes if they have a girl. However, males are favored in good environmental conditions because they have a better chance of copulating with multiple females (the males' act does not require a long gestation period). Ergo, they are a riskier proposition, but one worth taking, which is likely why at sexual maturity the ratio of males to females is roughly equal.
in humans gender is not fluid!

+Mikkel D. Watch the video. You are either XX or XY. There's no in between. Gender identity is largely defined by culture, not biology.

A long time ago this was actually my first ted video and I hadn't yet realized it though
Damn that ants part is so interesting
Congratulations on the baby boy.
I've read that the chances of having a boy or girl are more like 51/49, due to the slightly smaller sperm head of the Y sperm (Y chromosomes are smaller than X chromosomes, so the sperm head is smaller for Y than for X). The smaller sized head makes it easier and faster for the Y sperm to reach the egg than for the X sperm.
Simple yet very informative. Great video 👍
3:59 "they are all hot chicks and cool dudes" XD maybe that's where human got these terminologies
This is amazing! I can't stop watching these videos!!! I wish my brain wouldn't just store this information uselessly and make me viably smarter...

The quality and extent of that integration depends on the 1. neuroplasticity of your brain (which depends on how often you learn new things- it can be trained) and 2. the amount of pre-existing structures which are easily relateable to the newly aquired information.
I'm surprised they didn't speak on intersex people.
I hope it's still the same in 2022

Still My Favourite Ted Ed Episode After All These Years ❤
I wish they'd mentioned that a lot of people don't think it's accurate to describe workers in eusocial insect species as female. It's more accurate to describe ants, bees, etc as having three sexes rather than two. In a lot of ways, queens and males have more in common with each other than with workers. For example, in ants, both queens and males are born with wings and lose them after mating, whereas workers never have wings. In addition, both queens and males basically just sit around doing nothing but reproduction, while workers have jobs.

+Jonas Anselmo the Y chromosome I think always makes someone a male, biologically.
haha, its funny how the LGBT propaganda change people's mind like a religion. when you have more than two sex chromosomes it means this is a deformation, its innormal. im not saying its wrong but just its a very small fraction of babies who havd that combination as only less than 0.2% have the chance to have xxy and most of them are infertile
Not exactly. A fetus needs a surge of certain hormones at a certain stage of development in order to develop male features. Otherwise you get a genetic male that has the XY chromosomes but is physically a sterile female
