Buy Hackshot 2.0 which has 50% more questions from NCERT compared to this video, NCERT covered in more depth, and no mistakes, from Parth Goyal App. - ygkmg.on-app.in/app/oc/391746/ygkmg? Corrections - 8:01 These are spermatogenesis stages not gametogenesis 10:30 Oogenesis is initiated during the fetal life not after birth or puberty 49. The answer is secondary spermatocyte 94. Relaxin is secreted by the ovary not the placenta 97. Immediately after implantation only ectoderm and endoderm differentiate Explanation of some questions - 5. No. of lobules = 250 and each lobule contains 1-3 seminiferous tubules so the total no. of seminiferous tubules in a single testis = 250-750 51. Spermatogenesis is the process of formation of sperms from male germ cells while spermiogenesis is a part of spermatogenesis that represents the formation of sperms from spermatids thus the answer to this question will be spermiogenesis. 66. In question total primary follicles are asked so the answer will be double of the no. of follicles in each ovary i.e. - 1,20,000 - 1,60,000
The statement is incorrect. Secondary spermatocytes do not have the same DNA content as spermatogonia. Here's a breakdown of the DNA content during spermatogenesis: * Spermatogonia: These are diploid cells, meaning they have two sets of chromosomes (2n). They have the full complement of DNA. * Primary Spermatocytes: These cells are also diploid (2n) and have the same DNA content as spermatogonia. * Secondary Spermatocytes: These cells are haploid (n), meaning they have only one set of chromosomes. They undergo meiosis I, which reduces the chromosome number by half. Therefore, they have half the DNA content of spermatogonia. In summary, secondary spermatocytes have half the DNA content of spermatogonia. 👇
It is correct because 60 to 80 thousands primary follicles is present in each ovary and if you will calculate for the total sum 60+60k--80+80k= 1,20,000- 1,60,000
Answer to question no. 50 would be false and not true...since Dna content as well as chromosome no. becomes half in case of secondary spermatocyte...if it had been primary then it would have been same.
This is super helpful...if u have read ncert properly n when u r thinking to read again bcz that thought of forgetting everything is always there n then when u attend this session the whole chap comes in ur mind...best revision in the form of fully ncert based questions ❤️✨thanqq so muchh for this sir
Sorry you are wrong, remember that first, spermatogonia undergoes mitosis to form primary spermatocyte In this process the DNA content is doubled Then meiosis happens, primary spermatocyte gets converted into secondary spermatocyte and then the DNA content gets reduced to half. so whatever doubling happened during mitosis is reversed during meiosis and as a result, there is no change in DNA content.
Bhaiya in the Q 94 there should not be 5 hormones secreted by PLACENTA because Relaxin is a hormone secreted by OVARY Plz reply ,btw your these kind of videos are very much helpful for Revision ❤
Thank you bro ❤by this i fully revised the chapter and from 80 i got 71 Marks 😊 In class test thank you very much 🎉 may god bless you ❤️ and make such this type of video 📸 for revision ❤

Question 94 relaxin is secreted by ovary
Yes corpus luteum
But it can also be secreted by placenta go through n

@@AnujGupta0426 correct both placenta & ovary can secret relaxin..
Only secreted during pregnancy

Answer to question no. 50 would be false and not true...since Dna content as well as chromosome no. becomes half in case of secondary spermatocyte...if it had been primary then it would have been same.
Exactly I was thinking that too..
Thank you ❤
Study cell cycle and division properly
Bhaiyya it's false
Since meiosis takes place in primary spermatocyte

95. Relaxin is secreted in latter phase of pregnancy not during pregnancy
94) Relaxin is secreted by Ovary not by Placenta 🙃
yes
Haa
But releass during gestation period
During parturition from ovary
Both secrets
Q.49 skip hogaya...answer kya hai?

question no. 50 .... dna content reduced to half after meiosis
@@jahanvi216 hello
@@jahanvi216 spermatogonium contain 46 chromosome....but spermatogonia and secondary oocyte content 23 chromosome
Sorry you are wrong, remember that first, spermatogonia undergoes mitosis to form primary spermatocyte

Then meiosis happens, primary spermatocyte gets converted into secondary spermatocyte and then the DNA content gets reduced to half.
so whatever doubling happened during mitosis is reversed during meiosis and as a result, there is no change in DNA content.

Only 4 hormones h iske ans me bhi, it's a pyq
Bhaiya primary follicals 60,000-80, 000 left at each ovary na but you said 1,60000-1, 80000 pls ans the question bhaiya
Yes uh are right total primary follicle at puberty are 60k-80k
He misunderstood at the time of birth it's a couple of million primary follicle
the question is total no of primary follicles in the human body, so both ovaries are included, which makes it 120000-160000
