Question

Two individuals who are heterozygous for both genes in a dihybrid cross mate. What are the chances that their offspring will also be heterozygous for both genes? (Type answer as a decimal)

Answer 1

The probability that the offspring of the parents who are both heterozygous in a dihybrid cross are also heterozygous for both genes is 0.25

What is a dihybrid cross?

A dihybrid cross is a cross in which two different traits are involved in the crossing.

For example, the trait for height and color of hair in two parents being crossed is a form of a dihybrid cross.

Assuming two two traits are Ss and Yy, where the dominant traits are S and Y and the recessive traits are s and y.

The two individuals are heterozygous for both genes means that their genotype are both SsYy.

The dihybrid cross is shown in the attached image;

Based on the attached image, the heterozygous offspring for both genes SsYy are 4 out of the possible 16 offspring.

The probability of offspring that are heterozygous for both genes = 4/16 = 0.25

In conclusion, in a dihybrid cross, two traits or genes are involved in the cross and a possible number of 16 offspring are produced from the cross.
