Both fish seen here are African zebra cichlids. They have two color alleles. The allele for blue coloration is B, while the gene for orange coloration is O. A fish that has both types of alleles will be marbled orange and blue. This type of fish is not shown in the picture. Suppose that a male with genotype BO mates with a female that is also BO. What percentage of each PHENOTYPE will their offspring have?
A) 25% blue; 50% marbled; 25% orange
B) 25% BB; 50% BB, 25% BB
C) 50% blue; 50% orange
D) 50% BB; 50% BO

answer:

The answer to your question is B. 25%BB 50% BB 25% BB. Hope it helps and have a good day!

not the best question format lol but what i think might as scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. when moths that are homozygous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales.

the atmospheric gas that forms a mild acid when dissolved in water is called carbon dioxide. the correct answer is a. 2.) chemical weathering would cause an inscription on a marble headstone to become harder and harder to read over time.
