Question

in a group of cows, some individuals have solid coloring and others have white spots. in this group, the gene for the coat pattern trait has two alleles. the allele a is for solid coloring, and the allele a is for white spots.
prancer, a cow from this group, has white spots. prancer has two alleles for white spots.
based on this information, click the blue words to correct any errors in the text.
prancers phenotype for the coat pattern trait is solid coloring.
prancer is heterozygous for the coat pattern gene.
prancers phenotype for the coat pattern gene is aa.

Explanation:

1. Prancer has white spots (given it has two alleles for white spots, and allele \( a \) is for white spots). So the phenotype "solid coloring" is wrong; it should be "white spots".
2. Prancer has two alleles for white spots (genotype \( aa \)), so it's homozygous (same alleles), not heterozygous (different alleles).
3. \( aa \) is a genotype (genetic makeup), not a phenotype (physical trait). The phenotype here is "white spots", and \( aa \) is the genotype.

Answer:

1. For "Prancer's phenotype for the coat pattern trait is solid coloring", the blue word "solid coloring" should be corrected to "white spots".
2. For "Prancer is heterozygous for the coat pattern gene", the blue word "heterozygous" should be corrected to "homozygous".
3. For "Prancer's phenotype for the coat pattern gene is aa", the blue word "aa" (as a phenotype description) should be corrected to "white spots" (and note \( aa \) is genotype, but the question's context has "aa" as the blue word for phenotype, so correct the phenotype term to "white spots").
