Question

the passage describes the coat graying trait in horses.

most horses may turn gray or white as you grow older. some horses go through a condition process called coat graying as they age. these horses are usually a darker color, such as brown or black, when they are born. over time, the hairs of their coats lose their original color and become gray or white.

in a group of horses, some individuals have coat graying and others do not. in this group, the gene for the coat graying trait has two alleles. the allele g is for having a graying coat, and the allele g is for not having a graying coat.

daffodil, a horse from this group, has coat graying. daffodil has one allele for having a graying coat and one allele for not having a graying coat.

based on this information, what is daffodil’s genotype for the coat graying gene?

not having a graying coat

Explanation:

Step1: Identify alleles for Daffodil

Daffodil has one allele for graying coat (G) and one allele for not graying coat (g).

Step2: Determine genotype

Genotype is the combination of alleles. So with alleles G (graying) and g (not graying), the genotype is $Gg$.

Answer:

$Gg$
