Sep 23, 2015  · It functions the same in most organisms but the further apart two organisms are on the evolutionary tree the more DNA mutations have occurred. So by using genetics analyzing the number of differences in a gene (like cytochrome c) scientists can determine roughly how related two organisms are to eachother.

How Do Scientists Study Human Genetic Variation? Two research approaches were historically important in helping investigators understand the biological basis of heredity. The first of these approaches, transmission genetics, involved crossing organisms and studying the offsprings’ traits to develop hypotheses about the mechanisms of inheritance.
