MULTIPLE ALLELES Flashcards
A gene that is controlled by more than two alleles.
MULTIPLE ALLELES
are chemicals that induce an immune response to a body or substance in blood.
ANTIGENS
recognize and counteract against foreign & unfavorable substances to the blood
ANTIBODIES
is a gene that has more than two possible alleles (versions). Unlike simple Mendelian traits, which have only two alleles (one from each parent),
have three or more possible forms of the gene within a population.
MULTIPLE ALLELES
Multiple alleles increase genetic diversity because they
OFFER MORE POTENTIAL COMBINANTION OF ALLELES
This diversity leads to a _____ _____ __ __________ within a population, allowing for adaptation to changing environments.
