Answer:
50% or 1/2
Explanation:
<em> chance that they would have children with albinism is 50.</em>
A allele encodes normal pigmentation.
a allele encodes albinism.
An aa individual has children with an Aa individual
aa x Aa
Offspring = Aa, aa, Aa, and aa = 2 Aa + 2 aa (See the attached Punnet's square)
Based on the assumption that the A allele is dominant over the a allele, Aa individuals will have normal pigmentation while aa individuals will be albinos.
Hence,
<em>Percentage of their children that will have normal pigmentation </em><em>(Aa</em><em>) = 50% or 1/2.</em>
<em>Percentage of their children that will be albino (</em><em>aa</em><em>)= 50% or 1/2.</em>
