What is the genotype of the second sibling (daughter) if the below pedigree is for albinism?

The answer to this is Aa. This means that albinism will be a recessive trait for the daughter. The daughter might be a carrier of this condition and if she would be partnered with another person who will also have this recessive trait or perhaps, dominant trait, then it is more likely for their offspring to become affected by albinism.

Genetics has been studied for a long time and this has also helped people determine if they are adopted or not based on the details that they have learned. There are also some who have realized that they cannot be part of the same family because of the differences in their features and so much more.
