Question

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

Explanation / Answer

inherited in a complete dominant pattern. fishes with blue stripes and fishes with yellow stripes

inherited in an incomplete dominant pattern. fishes where the two alleles blue and yellow are showing incomplete dominancde and will appear green and striped.

inherited in a codominant pattern. fishes with both blue and yellow stripes are seen

the genotype of each of the parent fish, BB, YY,

the genotype of the offsprings will be blue will be BB, yellow will be YY, green will be By and blue and yellow BY
