relatively constant for a long period of time
14 spontaneous changes in genes or chromosomes
15 reproductive isolation which negatively affect the viability
and fertilization of hybrids
16 variations that are beneficial to organisms in certain

small variations from generation to generation

the inheritance of________characteristics
