Q. A change in the amount of yolk and its distribution in the egg will affect:

A) Pattern of cleavage
B) Number of blastomeres produced
C) Fertilization
D) Formation of zygote
Explanation

[Solution from source] Yolk slows down cleavage furrows, so the amount and distribution of yolk decide whether cleavage is holoblastic or meroblastic, equal or unequal. Fertilisation and zygote formation do not depend on yolk distribution. Answer (1).
