What was one of the conclusions of the Modern Synthesis? |
-Gradualism was supported -heredity was the same for discrete and continuous traits -microevolution leads to macroevolution -mutation is the raw material for natural selection, not an alternative to it -Lamarckian ideas were rejected -strictly mutational ideas about the mechanisms of evolution were rejected |
|
|
What is one explanation for why we see continuous variation? |
-Environmental effects -co-dominant alleles -multiple genes that influence a single trait -epistasis -recombination and sex |
