1. Is it true that a homozygous dominant father and a homozygous recessive mother could give birth to a homozygous recessive child with the disorder phenotype? Explain.
From the information provided, it can be determined that this statement is not true, as the offspring of this couple will not be homozygous recessive for the given trait. As both of the parents are homozygous for their respective alleles, every child would receive an allele from each parent, one being dominant (D) and the other being recessive (d). The resulting offspring would all be heterozygous dominant for the trait (Dd). (O'Neil 2012). This means that while the offspring would have the recessive gene in their DNA, they would not express it, and therefore only be carriers
