Albinism results from a recessive allele. Which of the following describes the expected offspring from a normally pigmented male with an albino father and an albino wife?

Question

Quizplus · Accepted Answer

The normally pigmented male would be homozygous dominant (AA) for pigmentation. His albino father must be heterozygous (Aa) since he carries one copy of the recessive allele. The albino wife must be homozygous recessive (aa). Therefore, the Punnett square would be:
```
|  A  |  A  
-----------
a | Aa  |  Aa
a | aa  |  aa
```
The offspring would be 50% Aa (normal) and 50% aa (albino).
