Question

Galactosemia is an inherited genetic condition. Children with this condition cannot break down the sugar galactose, which is part of lactose. Based on the pedigree chart, is this condition a dominant or a recessive disorder? Explain your reasoning.

Answer 1

Recessive.

Step-by-step explanation:

Galactosemia is an autosomal recessive genetic disorder. Recessive genetic disorders occur when an individual inherits a non-working gene from each parent.

There is no chart attached, so the reasoning is just common scientific knowledge. Please attach the chart so I can properly answer the question!

Answer 2

It is recessive. Both parents are heterozygous for the trait, but they do not exhibit the disease themselves. If it were a dominant gene, both parents would have the disease if they carried the gene for it.
