ii) 'e' from 'd'.
iii) 'd' from 'b'.
(b) Identify 'a', 'b' and 'c'.
Answer :
(a)
i) ‘b’ (secondary spermatocytes) formed after first meiotic division/Meiosis -I in ‘a’ (primary spermatocytes)
ii) ‘e’ (sperms) formed via a process called spermiogenesis/differentiation from ‘d’ (spermatids)
iii) ‘d’ (Spermatids) formed after second meiotic division/ Meiosis- II from ‘b’ ( secondary spermatocyte).
(b)
a – Primary spermatocyte
