Expert Solution

We need to find out the fraction of offsprings having the geotype DDEeffgg from the cross DdEeFfGg X DDEeffGg. The multiplication rule can be used to solve this, by calculating the probability of the individual events and then multiplying the obtained result to get the probability of the events occuring together.

Fraction of offspring with the genotype DD can be calculated from the following cross-

D d
D DD Dd
D DD Dd

So, the fraction of the offspring with the genotype DD is 2/4 or 1/2

Similarly, fraction of offspring with genotype Ee can be calculated as below-

E e
E EE Ee
e Ee ee

The fraction of the offspring with genotype Ee is 1/2

Fraction of offspring with genotype ff-

F f
f Ff ff
f Ff ff

1/2 of the offspring will have the genotype ff.

Fraction of offspring with genotype gg-

G g
G GG Gg
g Gg gg

1/4 of the offspring will be having the genotype gg.

Therefore, fraction of offspring having the genotype DDEeffgg will be- 1/2 X 1/2 X 1/2 X 1/4 = 1/32
