Explanation:
Detailed explanation-1: -A duck’s haploid cells contain 14 chromosomes.
Detailed explanation-2: -Therefore, a bird that has 80 chromosomes in a typical diploid cell would have 80 divided by two chromosomes in a typical haploid cell. So each of the pigeons’ gametes would have 40 chromosomes. So far, we’ve confirmed that a diploid body cell will contain twice the number of chromosomes of a haploid gamete.
Detailed explanation-3: -Somatic cells such as blood cells and muscle cells are diploids that have a total of 46 chromosomes.
