Mendel's experiment | Monohybrid Cross | Law of Segregation
HTML-код
- Опубликовано: 5 фев 2018
- CBSE class 10 Science - Heredity and Evolution -Mendel's experiment of Monohybrid Cross and Dihybrid Cross with pea plants gave an idea of how traits (characters) get expressed. After Monohybrid Inheritance experiment Mendel gave First Law of Inheritance (Law of Segregation). In Monohybrid cross Mendel found the Recessive Traits and Dominant traits present in the plants. With the help of the Punnett square we will find out why dwarfness was missing in the offsprings in the F1 generation and was present in the F2 generation.

Why did he pick a pea plant?.... It's an imp. Question....
1.because life span of pea plant is very short.
2.he could study a no.Of contrasting visible characteristics peas...-round or wrinkled seeds
-colour of flowers
-height of plant
3.easy to maintain
4.pea is a bisexual plant... Hence can easily cross breed and self pollinate....
Hope it helps❤🥰
Meenu Pandey another one of the reason is it is annual plant
Meenu Pandey another one is it can do self fertilization
It had 7 pairs of contrasting characters
Lifespan of pea Jo hoti h choti hoti h.

This Topic was so complicated to me but after watching this video of (PrepOnGo) this topic is clear to me. I appreciate your business and I hope you will make this kind of amazing videos further. And at last my board exams are coming and can you please make a video on discussing the last year board examination question paper. I hope You Find my request.
Thank you.
I REMEMBER I HAD STUDIED THIS HEREDITY AND EVOLUTION FROM THIS CHANNEL in class 10, whole chapter was in my fingertips 😄👆👆☝️👍👍

Mam how can we know self and cross pollination takes in this . Mam can u say answer.
Understood very well🤗🤗🤗
Thank you ma'am.
Nice work.
Thank you mam That you explained it broadly and conceptually ❤️
Wonderful explanation! I came across this video by chance. Very lucid, in even pace!
Thanks for teach me online.Thanks very much mam
Hey!! I have a question.
How did mendel come to know that the plants he took are pure bred short and tall respctvly???
Very nice question....
For this mendel has taken a Dwarf plant (for Dwarf plant only possible genotype is tt)
and crossed with a Tall plant(Possible genotype either Tt or TT)
If tall :Dwarf ratio in offsprings is 2:2 than it was a Impure tall and if the ratio is 4:0 than it was a pure tall plant
@blah blah 😂😂😂😂😂😂
🤔🤔🤔🤔
That's a point
Because this scientiests , are already mad and want to make us also mad , not only this scientiest but many more exams the scientist who invented gravity
By your video I learnt about mendal of experiment thank you so much mam
thanks a lot
your vedio helped me a lot.
Preparing for my boards tomorrow
nice class. i could cover every thing thanks for the video
thankuuuuu vry much.....vry well undrstood
Why can't all the progenies be short in F1 generation when crossed between pure tall and pure short plant?
Because tallness is the dominant trait
Tallness (T) is the dominant trait and ot expresses itself in the progenies formed (Tt)
Thank you so much ma'am for sharing this video .it's helpful
Good prepared with nice presantion,,thanks alot
Best way of teaching...Thank you😊😊

Bhai eng nhi aati toh na likha kro😜
I have a doubt mam that is in f1generationn all are yellow but we say that phenotype ratio in f1 generation is 3:1 how mam
Could you tell me why tallness is dominant not the dwarfness???
What determines the dominance of gene....
Who else prepare for 4 March 2020??
