Which is NOT a type of natural selection causing evolution?

• Normal

• Directional

• Stabilizing

• Disruptive

Sexual Selection

• A trend in the population towards a specific allele

• Mixing the genes from two populations together

• Some genes help improve mating success

Gene flow

• A trend in the population towards a specific allele

• Mixing the genes from two populations together

• Some genes help improve mating success

Genetic Drift

• A trend in the population towards a specific allele

• Mixing the genes from two populations together

• Some genes help improve mating success
