Final answer:

In a mating between a heterozygous individual and a normal homozygous individual, the genotypic and phenotypic ratios would both be 1:1. When mating a heterozygous individual with an individual homozygous for the defective allele, the genotypic ratio would be 1:1, and the phenotypic ratio would be 1:0.


Explanation:

Genotypic ratio:
a. 1:1
b. 1:1

Phenotypic ratio:
a. 1:1
