Question

suppose that you had a male mouse with black eyes and a female mouse with red eyes. you know that the allele for black eyes is dominant, and you want to determine whether the male is heterozygous. to do so, you would do a. breed them and look for approxi ratio of black eyes to red eyes. test cross simulation punnett square done

Explanation:

A test - cross is used to determine the genotype of an individual with a dominant phenotype. By crossing the individual with a recessive homozygous individual (the female with red eyes in this case), the resulting offspring ratios can indicate whether the dominant - phenotype individual is heterozygous or homozygous. If the male is heterozygous, the expected ratio of black - eyed to red - eyed offspring in a test - cross is 1:1.

Answer:
