A recessive allele can be characterized as a genetic variant that will only express a biological feature if it is coupled with a counterpart recessive allele. Learning disabilities, psychological, and impolite temperaments are all traits that recessive alleles may express in behavioral genetics. Retrieving genetic inheritance maps enables psychologists and geneticists unrestricted access when determining the relationship between personality, behavior, and the environment. Example: A gene for blue eyes can only be expressed if both parents possess the gene.
