Did you mean Genotype?

GlossaryGenotype

genetic composition influencing traits and characteristics

Genotype refers to the genetic makeup of an organism, specifically the set of genes it carries. It determines various traits and characteristics, such as eye color or susceptibility to certain diseases, by influencing how the organism's cells function and develop. For example, in the context of hair, a person's genotype can influence whether they are predisposed to conditions like alopecia.
