Question

The cromosome numberof sexualy reproducing parent and their offspring is the same.Give reason

Answer 1

In a diploid individual (2n) the sex cells(sperm,ovum) are haploid (n).This is due to reduction division/meiosis.

When haploid sperm and haploid ovum fuses during fertilization the resultant offspring will be haploid (n+n=2n)
