Thank you so much sir..there was so many confusions in mind before ,but now I got cleared about the gametogenesis after watch your video..ur teaching is really understandable soon..god bless you n keep uploading more videos sir.. thanks a lot again.👍👍
@@shomusbiologyofficial yes sir I follow your every vedio for my study ,I am zoology student of tripura ,,,I wish that you explain also much more zoology ,human physiology and botany topic ,,,,,yes all vedio really helpful for my study ,,,tnq sir 🙂
@16:50 Polar body and secondary oocyte will have same number of chromosomes because they are products of meiosis also if secondary oocyte will have any more than 23 chromosomes (humans) it will lead to chromosomal anomalies. @Shomu's Biology
Attachment of sperm with egg occurs at the fallopian tube. That creates d zygote. This moves through the fallopian tube. The cleavage occurs at d fallopian tube. After blastula is formed ,it contains trophoblast nd embryoblast, the zygote sheds of zona pellucida and gets attached to d ciliated wall of uterus( not attached in d fallopian tube) and then further deveolopment like placentatn will take place. Very nice informative video. Thank u for doing this.
Gurudev, for this reason?? The fishes need to copulate??unless the copulation of fish, they cannot produce eggs from secondary spermatocytes??? 🤔🤔isn't it??
Hi sir , thnx for this videos, itz really helped me for my study more accurately. But please I have a request , please make a special video of NEET EXAMINATION, how to focused on main points or thats type of topic . Thnx sir ,
awesome video .. I just noticed one thing .. spermatogonium is singular and spermatogonia is plural and the same for oogonium and oogonia but still thank you for this video .. good job :)
Please explain it a little aloud as it seems very difficult to hear the sound . Otherwise the video was absolutely perfect. Thank you very much but please explain it aloud
Very good overview, it is really helpful! But isn't it a MEIOTIC arrest in prophase I of the primary oocytes after birth? You wrote "mitotic" and now I am confused..
hi dear you are right, the arrest occurs after diplotene phase of prophase 1 of meiosis 1. During this arrested phase of development, the primary oocyte is surrounded by a layer of follicle cells and the oocyte along with the follicle cells is termed as primordial follicle. This primordial follicle further begins to develop and gets surrounded by multiple layers of follicle cells known as granulose cells, the oocyte also develops a thick ZONA PELLUCIDA layer and a basal lamina to separate it from the other cells in the ovary. So don't get confused I hope I cleared your doubt. Also meiosis 1 will get completed only when puberty hits and by the stimulation of the gonadotropins (Leiutinizing hormone and follicle stimulating hormone) which stimulate ovulation. The process of ovulation will then trigger the completion of meiosis 1 and finally the formation of the first polar body and secondary oocyte which will then undergo meiosis II to develop into a mature egg and second polar body. I really hope this helps :)
I have watched a video un that they said that there are some bodies who trap the sperms but the quantity if sperms is huge which cause fertilization to occur
Sir during spermatogenesis a man produces huge numbers of sperm in their life cycle and they have similar gene sequences similarly incase of women they releases total oocyte in their life cycle during menstruation are also similar in their gene sequences so why the first offspring and second offspring (except identical twins) shows genetic and morphologic variation even they were produced From same gene combination? Sir এটা কেন হচ্ছে যদি clearly bolen toh khub valo hai🙏🥰
No need to read from book after listening to the lecture . Thank u sir keep up good work ♥️
Glad to hear that you're getting benefit from my lectures
I am thankful to this RUclips page.

Thank you sir .Iam preparing zoology optional for civilservice , your vedios helped me a lot.thank you.
Sir you may start a new venture. Zoology optional subject coaching for civilservice....what u say?
Thank you Sir, you are One of the Best Teacher in RUclips
Thank you so much for appreciating my efforts. Glad to hear that you're getting benefit from my lectures

You're welcome
Ur teaching skills are awesome sir.. thank u so much
You're welcome. Glad to hear that you're getting benefit from my lectures
Woow very nice sir; u looking like a student sir 😊very simply explained all doubt sir thanks a lot 🙏😊🙏
You're welcome. Glad to hear that you're getting benefit from my lectures
SIR NO WORDS.Handsome.
Thank you
Thank you so much sir this is the best video in RUclips 😀
I appreciated , it was so easy to learn. thanks
u r simply awesome in bio ua patience knowledge reflects in every video tq
Sir first gonocytes are produced. Later they change into spermatogonia or oogonia.
Gurudev, for this reason?? The fishes need to copulate??unless the copulation of fish, they cannot produce eggs from secondary spermatocytes??? 🤔🤔isn't it??
Hello sir...Ur teaching style is simple n excellent.
+Padmini Harish thank you.
Hi sir , thnx for this videos, itz really helped me for my study more accurately. But please I have a request , please make a special video of NEET EXAMINATION, how to focused on main points or thats type of topic .
Thnx sir ,
+Ayan Ayan Saha Saha I was preparing the series for NEET
Great video.... Keep up the enthusiasm.
awesome video .. I just noticed one thing .. spermatogonium is singular and spermatogonia is plural and the same for oogonium and oogonia
but still thank you for this video .. good job :)
ramez al-khalaf yes u r right
Thank you sir..its really helpfull...
You're welcome
thank you sir
You're welcome
Please explain it a little aloud as it seems very difficult to hear the sound .
Otherwise the video was absolutely perfect. Thank you very much but please explain it aloud
sir total of how many sperms and eggs are produced during spermatogenisis and oogenisis.
You are a legend..💜
magnificent! thank you very much sir :)

Thank you
Ultra legends watching after 10 yrs❤
Thank you sooooooo much sir....it was really very helpful....
please make a different video for hormonal regulation
Tq sir
You're welcome
Very helpful. Tankuuuuuu so much.....
one QUESTION "Why sperm is not acting as an antiboby in female reproducting system during coupling ?"
not antibody... it acts like antigen.!!
I have watched a video un that they said that there are some bodies who trap the sperms but the quantity if sperms is huge which cause fertilization to occur
Sorry sir primary spermatocytes first changes into secondary spermatocytes
That part doesn't seem to be important. It's not in my notes. It says that it goes straight from primary to 4 haploid spermatids
Yea, by meiosis,
Both mitosis and meiosis happens in process of spermatogenesis
Sir than what is secondary spermatocyte?
Plz guide me
than you for this video. please keep it up.
Sir kindly tell what's the meaning of mitotic arrest
Satti asadharan vedio ..sirrr
Thank you
nice video. lt is easy to understand
good video ) thanks

Sir এটা কেন হচ্ছে যদি clearly bolen toh khub valo hai🙏🥰
ty so much
thank you sir........
the formation of spermatids is by meiotic division 1 and 2...didn't expect this mistake from u😞
Very niceee ...
Tq sir....
first time I found your lecture boring.
u made it very lenghty
thank u sar...
ESCs are pluripotent, not Totipotent.
Long live sir g
Thank you
Is it meiotic arrest or mitotic arrest??
mitotic arrest
because meiosis only occur when both different gametes fuse to form New one
Priya Negi it is meiotic arrest , as he also said mitotic prophase 1, whereas there is no prophase 1 n 2 in mitosis
Xllent sir
ITS spermatogonium is singular and spermatogonia is plural
thank yew sir
after zygote t it transfer to uterus
correct the spelling of "Mamals" in the title.
xlent sir
Primary spermatocytes matuers to secondary spermatocytes.
Yes
Ium = singular
Ia = plural
+
You forgot about secondary spermatocyte :(
why do u have headphones on >

Sir ne padhaya to badhiya h magar mic ke sath m headphone kyu pehne hai 😂
Check the date of the upload. You didn't even know about RUclips then
@@shomusbiologyofficial arre sir i am just jocking muje pta h aap abhi boht pragatee kar chuke he don't be serious
By the way big fan 🌹🌹
why u r using Arrest Encounter like this words
are You.police or Biologist
#Just kidding
great perform
Sometimes for a person it is difficult to speak in languages like English... I also face the same problem during seminars..
he is confused
