Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

If a sexually reproducing organism has 28 chromosomes in its body cells, how many chromosomes did it inherit from each parent?

A	7
B	14
C	16
D	28

Explanation:

Detailed explanation-1: -Answer and Explanation: If a parent cell has 28 chromosomes and undergoes meiosis, the resulting cells will have (c) 14 chromosomes.

Detailed explanation-2: -If a diploid cell containing 28 chromosomes undergoes meiosis, how many chromosomes will each daughter cell have? EXPLAIN. Each daughter cell will have 14 chromosomes. Meiosis results in haploid gametes, meaning each gamete will have half the original number of chromosomes as the diploid parent cell.

Detailed explanation-3: -Somatic cell or normal body cells contain 28 pair of chromosomes. Therefore, 28*2 = 56 chromosomes (as one pair is equal to two chromosomes). Germ cells are haploid in nature therefore they contain only 28 chromosomes (not in pair, but singly).
