LIFESCI 7B Study Guide - Midterm Guide: Natural Selection, Heritability, Sickle-Cell Disease
Document Summary
Natural selection tries to filter to bebad more selection. 0 change the mean trait value in genetic favors middle aitteaminin"t variation d genetic variation mean stays the same. Sympatric same place separated can interbreed disruptive select. Peripatric small portion ofpop moved population is another fixed it one allele is is 0. Direct what you pass down indirect genes shared w. Inclusive all genes passed down t relatives shared up relatives.
