Math Equation Response Question
Some people have earlobes that are attached to the skin of their necks, while others have earlobes that are unattached. In human beings, having unattached earlobes (A) is a dominant characteristic over attached earlobes (a). The Punnett square below shows the genetic distribution of two parents, one with attached earlobes and one with unattached earlobes.
What is the percent chance that their offspring will have unattached earlobes?
To determine the percent chance that their offspring will have unattached earlobes, we need to evaluate the Punnett square provided.
If one parent has attached earlobes (aa) and the other parent has unattached earlobes (AA), the possible combinations of their genotypes in the offspring will be as follows:
- 50% chance of offspring having attached earlobes (Aa)
- 50% chance of offspring having unattached earlobes (Aa)
Therefore, there is a 50% chance that their offspring will have unattached earlobes.
