Question

9 "The chromosome number of the sexually reproducing parents and their offspring is the same.
Justify this statement​

Answer 1

Answer:

Gametes have half the number of chromosome. When they fuse, the original number is restored. At the time of fertilization male and female germ cells are fused to form a zygote. Therefore, the chromosome number of sexually reproducing parents and their offsprings is the same.

Answer 2

Answer:

During fertilisation, the fusion of male and female gametes takes place, which results in the number of chromosomes in the zygote to be equal to that of somatic cells. Thus, the chromosomal number of the sexually producing parents and their offspring is the same.
