Detailed explanation-1: -The normal body cell of an organism contains 28 pairs of chromosomes. The number of chromosomes present in its germ cell will be : (a) 28.
Detailed explanation-2: -SOLVED: An organism has 28 pairs of chromosomes in its diploid somatic cells.
Detailed explanation-3: -The normal body cell of an organism contains 28 pairs of chromosomes.
Detailed explanation-4: -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).
Detailed explanation-5: -The Number of Chromosomes (n-Value) Human gametes contain 23 chromosomes. We can summarize this statement as 1n = 23 where n is the n‑value, the number of chromosomes in a gamete. When a 1n = 23 sperm fertilizes a 1n = 23 egg, the zygote will be 2n = 46.
