The diagram shows one process during sexual reproduction. after fertilization, the zygote contains 28 chromosomes. what is the number of chromosomes (n) present in the gametes? a) 7 b) 14 c) 28 d) 56

The correct answer would be B) 14.

In sexual reproduction, gametes are haploid cells formed after meiotic division of germ cells.

Meiosis is a cell division which results in the formation of four daughter cells from a single parent or germ cell. Each daughter cell contains half the number of chromosome present in the parent cell.

The haploid gametes fuse to form diploid zygote that is, the fertilization restored the diploid chromosomal number.

Now, the number of chromosomes in the zygote is 28. Thus, the number of chromosomes in gametes must be half of 28 that is, 14.
