A recessive allele causes syndrome H. A heterozygous woman and a homozygous recessive man want to have a child. Draw a Punnett square diagram to determine the probability of the child having syndrome H. Identify any children with syndrome H. Use the following symbols: A = dominant allele a = recessive allele Probability = _______ % – 7074

1. Mother’s gametes: A and a
   Father’s gametes: a and a
   Offspring genotypes:
   Aa
   aa
   aa
   Aa
   So, 2 out of 4 (50%) have genotype aa, which means they have syndrome H.
