Heterozygous
parents have genotype Aa. If we cross two of them then:
<span>Parents:
Aa x Aa</span>
<span>F1
generation: AA Aa Aa aa</span>
<span>This
means that the <span>chances of having a child with the disease
are ¼ (or
25%) and that is the child with genotype aa (homozygous recessive).</span></span>
