Homozygous Recessive
aa
Homozygous recessive refers to the inheritance of two copies of a specific recessive genetic trait from each parent. In this case, the individual has two identical copies of the recessive allele that codes for the trait. Homozygous recessive individuals express the recessive trait because there is no dominant allele to mask or suppress it.
For example, if we consider a particular recessive genetic trait associated with hair color – brown hair as dominant and blonde hair as recessive. A homozygous recessive individual would inherit two copies of the recessive allele, one from each parent, resulting in blonde hair phenotype. In contrast, a dominant phenotype would occur in an individual having at least one copy of the dominant allele.
Homozygous recessive can also refer to genetic disorders where the person inherited two mutant copies of a specific gene associated with a particular disease, resulting in the expression of the disease phenotype. It is important to note that a person who is homozygous recessive for a particular trait does not necessarily carry or transmit the condition to their offspring.
