Rotating Around Branch Points Fishes Frogs Rotation Rotating the branches of a tree around a branch point does not change what they convey about evolutionary relation- ships. As a result, the order in which taxa f you rotate the branches of the tree at left around the three blue points the result is the tree at right Frogs Humans Lizards Chimps appear at the branch tips is not significant. What matters is the branching pattern, which signifies the order in which the lineages have diverged from common ancestors. Chimps Lizards Humans Fishes Note The order of the tasa does NOT repreent a seguence of evolution Teading to the last taxon shown (n this tree, human) S. Redraw the tree above, rotu around the green branch po Identify the ban closest reatve humans as shoun in each of three trees Explain your an 4.

Genetic Variation

Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.

Quantitative Genetics

Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
