Did you mean Homozygous?

GlossaryHomozygous

having two identical alleles for a specific gene

Homozygous refers to having two identical alleles for a particular gene. In simpler terms, if you inherit the same version of a gene from both your mother and your father, you are homozygous for that gene. This can influence traits such as hair color or susceptibility to certain conditions like alopecia. For example, if both alleles for a gene related to hair growth are the same, it can determine whether you have a full head of hair or are more prone to hair loss.
