Problem:

It can be challenging to distinguish different forms of genetic inheritance. Consider a fish that exhibits different phenotypes in the stripping pattern on its body. The character is controlled by a single gene, with only two alleles, SB and SY.

One parent is homozygous for one of the alleles for this gene, SB, and exhibits a phenotype in which two vertical blue stripes are present. The second parent is homozygous for the other allele for this gene, SY, but they exhibit two yellow vertical stripes.

What is your prediction for the phenotype of the offspring of these fish if the gene is .....

1.) Inherited in a complete dominant pattern.

2.) Inherited in an incomplete dominant pattern.

3.) Inherited in a codominant pattern.

4.)Regardless of the phenotype, what is the genotype of each of the parent fish, and what is the genotype of the offspring?

Give reasoning with your answer.
