Question

this passage describes the coat pattern trait in cheetahs: a cheetah with a spotted coat has many small black spots on its body. a cheetah with a king coat has large black splotches on its body and stripes on its back. king cheetahs are rarely seen in the wild. they were once thought to be a different species. in a group of cheetahs, some individuals have a spotted coat and others have a king coat. in this group, the gene for the coat pattern trait has two alleles. the allele for a spotted coat (a) is dominant over the allele for a king coat (a). this punnett square shows a cross between two cheetahs. punnett square with rows labeled a and a, columns labeled a and a; cells: top-left aa, top-right aa, bottom-left aa, bottom-right aa what is the probability that a cheetah produced by this cross will have a king coat? options: 0%, 25%, 50%, 75%, 100%

Explanation:

Step1: Identify king coat genotype

King coat is recessive, so genotype is $aa$.

Step2: Count total Punnett square outcomes

Total possible genotypes: $4$ (Aa, Aa, aa, aa)

Step3: Count king coat outcomes

Number of $aa$ genotypes: $2$

Step4: Calculate probability

$\text{Probability} = \frac{\text{Number of } aa}{\text{Total outcomes}} = \frac{2}{4} = 50\%$

Answer:

50%
