yellow
black
brown

Explanation:

Step1: Determine the genotypes for each phenotype

• Yellow: \(Bbee, BBee, Bbee, bbee\). Count the number of these genotypes in the Punnett square. There are \(4\) such genotypes. So the proportion is \(\frac{4}{16}\).
• Black: \(BBEE, BBEe, BbEE, BbEe, BbEE, BbEe, BbEe, BbEe\). Count them: there are \(9\) genotypes. So the proportion is \(\frac{9}{16}\).
• Brown: \(bbEE, bbEe, bbEe, bbEe\). Count them: there are \(3\) genotypes. So the proportion is \(\frac{3}{16}\).

Answer:

yellow: \(\frac{4}{16}\), black: \(\frac{9}{16}\), brown: \(\frac{3}{16}\)
