For children who do not have galactosemia, what are their possible genotypes for this trait?

a pedigree chart for the inherited genetic condition galactosemia

heterozygous

homozygous dominant

homozygous recessive

no inheritance for this trait

its heterozygous and homozygous dominant

The correct answers are "heterozygous", and "homozygous dominant".

Explanation:

Galactosemia is a condition where people are not able to process the sugar galactose. People with this condition have one gene mutated, which does not allow the proper synthesis of the enzyme that breaks down galactose. Galactosemia is inherited as an autosomal recessive genetic condition, therefore, only children that are homozygous recessive develop the condition. Children that are heterozygous or homozygous dominant, will not develop galactosemia.
