It is the primary mechanism for evolution
Answer:
<em>There is a 25% chance of an offspring having blue eyes.</em>
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:
- <em>there is 25% chance that the offspring will be homozygous for brown eyes.</em>
- <em>there is a 50% chance that the offspring will be heterozygous for brown color.</em>
- <em>there is a 25% chance that the offspring will be homozygous and have blue eyes. </em>
