Draw a Punnett square to show how to parents with normal skin color could have an albino baby

Parents with normal skin colour will have an albino baby if both of them are heterozygous for the trait.

Explanation: A parent who is heterozygous will have one dominant allele (A) for normal skin colour and one recessive allele (a) for albinism. If both of them are heterozygous for the trait, there is possibility of them producing an albino baby.

_ A a

A AA Aa

a Aa aa

The cross produces one homozygous normal skin coloured baby (AA), two heterozygous normal skin coloured babies (Aa)- and one albino baby (aa).
