Question

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

Explanation:

Step1: Count the total number of offspring

There are \(4\) boxes in the Punnett square, so there are \(4\) possible offspring.

Step2: Count the number of offspring with blue eyes

The offspring with genotype \(bb\) have blue eyes. There are \(2\) \(bb\) genotypes in the Punnett square.

Step3: Calculate the probability

The probability formula is \(P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). Here, \(P = \frac{2}{4}\). Simplifying \(\frac{2}{4}\) gives \(P=\frac{1}{2}= 50\%\)

Answer:

\(50\%\)
