Welcome to the NCERT Solutions for Class 11th Biology - Chapter Cell cycle and Cell Division. This page offers a step-by-step solution to the specific question from Exercise 1, Question 9: find examples where the four daughter cells from m....
Question 9
Find examples where the four daughter cells from meiosis are equal in size and where they are found unequal in size.
Answer
(a) Spermatogenesis or the formation of sperms in human beings occurs by the process of meiosis. It results in the formation of four equal-sized daughter cells.
(b) Oogenesis or the formation of ovum in human beings occurs by the process of meiosis. It results in the formation of four daughter cells which are unequal in size i.e. are big mature ovum and 3 smell polar bodies.
