A plant species is described as 2n24 a How many chromosomes

A plant species is described as 2n=24.

(a) How many chromosomes present in a triploid cell from this plant?

(b) How many chromosomes present in a monosomic cell from this plant?

(d) How many chromosomes present in a nullisomic cell from this plant?

Answer:

a). 36

2n = 24

n= 12

Haploid= 12

Diploid = 2n = 24

Triploid = 3n = 36

b). Monosomic= 23

Monosomic= 2n-1 = 24-1=23

c). Double trisomic = 2n+1+1= 24+1+1= 26

d). nullisomic=2n-2= 24-2 = 22
