Answer:
Father= Aa (heterozygous carrier)
Mother= aa (homozygous recessive)
Lactose intolerant child = aa (homozygous recessive)
Explanation:
Lactose intolerance is an autosomal recessive trait. Let's assume that the recessive allele "a" is responsible for lactose intolerance while the dominant allele "A" gives normal phenotype. The mother is lactose intolerant and therefore, should be homozygous recessive since the recessive disorders are expressed in homozygous genotype only.
The genotype of the mother would be "aa". Father exhibits normal phenotype and therefore, may be homozygous or heterozygous dominant for the trait. However, since they have a "lactose intolerant" child (aa), the father should also have at least one copy of "a" allele. Therefore, the genotype of the father is "Aa" (heterozygous carrier).
