Question

1. in cats, pointed ears are dominant to round ears. a homozygous recessive cat (ee) is bred with a heterozygous cat (ee).

Explanation:

Step1: Determine the gametes

The homozygous recessive cat (ee) can only produce e gametes. The heterozygous cat (Ee) can produce E and e gametes.

Step2: Create the Punnett square

	e	e
e	ee	ee

Step3: Calculate probabilities

For pointed ears (Ee), there are 2 out of 4 offspring. Probability: $\frac{2}{4}\times100\% = 50\%$.
For round ears (ee), there are 2 out of 4 offspring. Probability: $\frac{2}{4}\times100\% = 50\%$.

Answer:

Pointed Ears: 50%, Round Ears: 50%
