If a recessive allele is lethal, how can it survive to be passed on to the next generation?
reduces variation and has a greater effect on small populations
may evolve into separate species
the creation on new species
heterozygous individuals are not affected
they have a common ancestor
organisms with favorable traits survive and reproduce
mutation
high biodiversity
