Question

PLEASE HELP!! 30 POINTS.

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

It’s definitely not genetic based on the chart, if there was a more in depth family tree of those affected it could still be genetic, if not, it then becomes a disorder from a malfunction in the child’s DNA

Answer 2

Answer: it is recessive.

Step-by-step explanation:

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.
