Answer :
The correct option is D. The cat's genotype for coat color is Ww is most likely true.
In a completely dominant inheritance pattern for coat color in cats, if the cat is heterozygous for the white coat color, it means the cat has one dominant allele and one recessive allele.
Dominant allele (W): White coat color
Recessive allele (w): Another color (e.g., non-white)
Analysis:
Option A: The cat's phenotype for coat color is WW.
- Incorrect: The phenotype refers to the observable traits, not the genotype. The genotype of WW would not show the heterozygous condition.
Option B: The cat's genotype for coat color is WW.
- Incorrect: The genotype WW represents a homozygous dominant condition, not heterozygous.
Option C: The cat's phenotype for coat color is Ww.
- Incorrect: Phenotype refers to the physical appearance, not the genotype. The phenotype would be the result of the genotype, not the genotype itself.
Option D: The cat's genotype for coat color is Ww.
- Correct: A heterozygous genotype for the white coat color is represented as Ww, where W is the dominant white allele and w is the recessive allele.
The ocmplete question is- Coat color in cats is determined by two alleles in a completely dominant inheritance pattern. Your cat is heterozygous for white coat color. Which of the following statements is most likely true?
A. The cat's phenotype for coat color is WW.
B. The cat's genotype for coat color is WW.
C. The cat's phenotype for coat color is Ww.
D. The cat's genotype for coat color is Ww.
