Question

practice: eye color
what is the chance of their children having brown eyes?
father
mother

Explanation:

Step1: Analyze the Punnett square

The Punnett square has 4 offspring genotypes: \(Bb\), \(Bb\), \(bb\), \(bb\).

Step2: Determine brown - eyed genotypes

Genotypes with \(B\) (dominant allele) show brown eyes. Here, \(Bb\) are brown - eyed. There are 2 \(Bb\) out of 4 total.

Step3: Calculate the probability

The probability is \(\frac{2}{4}=\frac{1}{2} = 50\%\)

Answer:

50%
