Question

List three points of similarities between spermatogenesis and oogenesis?


class 12th CBSE Biology sample paper

Answer 1

Spermatogenesis is the process in which an animal produces spermatozoa from spermatogonial stem cells by way of mitosis and meiosis. The initial cells in this pathway are called spermatogonia, which yield primary spermatocytes by mitosis.

.

Oogenesis is the process through which (ova) female gametes are formed and this female gamete is known as an ovum.

Spermatogenesis and Oogenesis have following similarities:
1)Both process occurs inside the gonads (testes and ovaries).
2)Both are completed in three phase ; multiplicative, growth and maturation phase.
3)Both process shows meiosis in maturation phase and produce haploid gametes

Answer 2

Answer:

Multiplicative, growth, and maturation. Both process occurs in the gonads.
