Answers

Answer 1
Answer:

Answer:

The correct answer would be C. Bb.

Heterozygous condition refers to the genotype in which a gene contains two different alleles.

In contrast, homozygous refers to the condition in which gene contains two identical alleles.

For example, TT and tt are homozygous genotypes whereas Tt refers to the heterozygous condition.

Similarly, genotype Bb consists of two types of alleles B and b. Thus, it represents a heterozygous condition.
Answer 2
Answer: It would be C.
Since one copy of the genes is healthy and the other one is affected.
It wouldn't be A or B since both genes are the same.
And you can automatically exclude D.
