Markus Pearson · Answer 1

Haploid - 13

Triploid - 39

Tetraploid - 52

Trisomic - 27

Monosomic - 25

Explanation:

A haploid organism has half the chromosome number of a diploid version, hence 26/2 = 13

A triploid organism has 3 sets of a haploid chromosomes, hence 13 x 3 = 39

A tetraploid is double of a diploid, 26 x 2 = 52

Trisomic organisms have one extra chromosome in addition to the normal diploid. Hence 26 + 1 = 27

Monosomic organism has one less chromosome than the normal diploid. Hence 26 - 1 = 25
