Question

If n=23, 2n=46, what will be the number of chromosomes if an individual is a) Mosomic b) Trisomic c) Tetrasomic d) Double Trisomic e) Nullisomic​

Answer 1

Answer:

option e

Explanation:

Answer 2

monosomic condition = 2n-1=46-1=45

nullisomic condition =2n-2=46-2=44

trisomic condition = 2n+1=46+1=47

tetrasomic  condition =2n+2=46+2=48

double trisomic condition =2n+1+1=46+1+1=48
