Apr 19, 2021 · Consequently, different heritable phenotypes can be produced from the same genetic background depending on prior events, and can contribute to heritable variation. Typically, epigenetic states are not as stable as genetic determinants, but they nevertheless can have a significant phenotypic impact and be inherited for several generations. Glossary. adaptive evolution: increase in frequency of beneficial alleles and decrease in deleterious alleles due to selection. directional selection: selection that favors phenotypes at one end of the spectrum of existing variation. diversifying selection: selection that favors two or more distinct phenotypes.Terms in this set (17) Which of the following pieces of evidence most strongly supports the common origin of all life on Earth? -all organisms reproduce. -all organisms use essentially the same genetic code. -all organisms have undergone evolution. -all organisms require energy. -all organisms show heritable variation.
