Suppose two D/d E/e F/f G/g H/h individuals are mated. What would be the predicted frequency of D/d E/E F/f g/g H/h offspring from such a mating?

Solution

Let us analyse the given data -

Genotype of parents - D/d E/e F/f G/g H/h

Genotype of offspring - D/d E/E F/f g/g H/h

Now, during crossing of parental genotype, the following alleles independently assort with each other -

D/d E/e F/f G/g H/h X D/d E/e F/f G/g H/h

During a cross of D/d and D/d, the percentage of offspring that will have the genotype Dd is 1/2.
During a cross of E/e and E/e, the percentage of offspring that will have the genotype EE is 1/4.
During a cross of F/f and F/f, the percentage of offspring that will have the genotype Ff is 1/2.
During a cross of G/g and G/g, the percentage of offspring that will have the genotype gg is 1/4.
During a cross of H/h and H/h, the percentage of offspring that will have the genotype Hh is 1/2.

Now,

Predicted frequency of D/d E/E F/f g/g H/h offspring = 1/2 * 1/4 * 1/2 * 1/4 * 1/2 = 1/128 = 0.0078
