Genes code for traits.
<u>Example:</u>
"Hair color" is a trait. There are many different varieties of hair colors (blond, brown, black, etc.). Therefore, there are multiple genes responsible for the trait of hair color (a blond hair gene, a brown hair gene, a black hair gene, etc.).

Hi!
The correct answer would be A.
<h3>Explanation:</h3>
As the allele P for polka dot is dominant to the allele p for solid color, it would yield a Polka dot tail in the individual in the presence of just one allele of P, while masking the effect of p for solid color.
So the possible genotypes and phenotypes would be as follows:
- PP (Polka dot tail)
- Pp (Polka dot tail)
- pP (Polka dot tail)
- pp (Solid color tail)
Following a cross by two heterozygous individuals, there would be 25 percent chance (1/4) of having the genotype pp , 25 percent (1/4) chance of having the genotype PP and 50 percent (2/4) chance of having the genotype Pp.
But the phenotype yielded by Pp and PP offspring would be polka dots, so there is a 75 percent (3/4) chance of having polka dot offspring, and 25 percent chance of having solid colored tail offspring.
