Biology Ch. 9 notes “Genetics” Mendel’s Laws

A sperm or egg carries only one allele for each inherited character because allele pairs separate (segregate) from each other during the production of gametes. This explains how a trait can disappear i ...

Genetic migration is about gene movement, rather than actual movement of organisms, and is referred to as gene flow. 2. Gene flow has two major effects on a population: a. ...
