Question

this punnett square shows a cross between two cats.
what is the expected ratio of offspring with chocolate fur to offspring with cinnamon fur to offspring with black fur?

Explanation:

Step1: Analyze the genotypes

Assume that \(B\) is dominant over \(b^{h}\) and \(b\), and \(b^{h}\) is dominant over \(b\). \(Bb^{h}\) - chocolate fur (since \(B\) is present), \(b^{h}b\) - cinnamon fur ( \(b^{h}\) is dominant over \(b\)).

Step2: Count the genotypes

There are \(2\) \(Bb^{h}\) (chocolate fur) and \(2\) \(b^{h}b\) (cinnamon fur). There is \(0\) black fur (assuming black fur would be \(BB\) or \(Bb\) if \(B\) was for black, but in our case no such genotype).

Answer:

\(2:2:0\)
