Question

practice: eye color
what is the chance of the children being homozygous recessive?

Explanation:

Step1: Count the total number of offspring

There are 4 offspring in the Punnett square.

Step2: Count the number of homozygous recessive offspring

There are 2 offspring with the genotype \(bb\) (homozygous recessive).

Step3: Calculate the probability

The probability is \(\frac{\text{Number of homozygous recessive offspring}}{\text{Total number of offspring}}=\frac{2}{4}\)
Simplify \(\frac{2}{4}=\frac{1}{2} = 50\%\)

Answer:

50%
