5 True/False questions
Natural selection → natural selection that is related to mating success includes the ability to locate males, courtship behaviors, ornaments the mates find attrative, etc.
sexual dimorphism → dirrences in size, color, shape, behavior, between the sexes. Ex. Red male cardinal, brown female cardinals.
gametic isolation → pre-zygotic barrier where mating may be attempted but morphological, physical factors prevent the act of mating.
sex, mating → combining existing alleles in new ways (crossing over, random fertilization, random allignment)
No evolution by selection → NO variation means....
