Answer 1

Answer:

There is a 25% chance of an offspring having blue eyes.

Explanation:

A punnet square can be described as a diagram which is made to check the outcomes of a cross.

In the scenario discussed in the question, only one trait is being studied. Such a cross is termed as a monohybrid cross.

As both the parents are heterozygous for the trait, hence the punnet square can be made as follows:

       B             b

B   BB            Bb

b   Bb            bb

The results of this punnet square show that:

• there is 25% chance that the offspring will be homozygous for brown eyes.
• there is a 50% chance that the offspring will be heterozygous for brown color.
• there is a 25% chance that the offspring will be homozygous and have blue eyes.
