17.1 Genes and Variation

17.1 Genes and Variation. Genetics Joins Evolutionary Theory. Darwin developed his theory of evolution without knowing how heritable traits passed from one generation to the next or where heritable variation came from. Researchers discovered that heritable traits are controlled by genes.

Genetic Variation in Populations

Genetic Variation in Populations. The Field of Biology that Studies Microevolution. Microevolution Takes place over a short amount of time Results in new characteristic Within a population. Macroevolution Takes place over a long amount of time Results in new species

Intro. to Evolution I: Chapter 16 Population Genetics

Intro. to Evolution I: Chapter 16 Population Genetics. How do we get new species?. Breeders have been affecting plant and animal populations for centuries through artificial selection. Genetic variation in populations allows breeders to change gene pools.

How do new species arise? Speciation

How do new species arise? Speciation . What is a species? A group of organisms that can breed with one another to produce fertile offspring. Species share the same gene pool. Question: How to classify a mule?. Kingdom: Animalia Phylum: Chordata Class : Mammalia

Evolution in populations

Evolution in populations. Think Change over loooong periods of time. Gene pool: all the genes in a population. Not just the genes, but the variation of genes Allelic frequency; distribution of alleles. A population whose allelic frequency is not changing is in genetic equilibrium

Natural Selection and Gene Flow

Natural Selection and Gene Flow. Allie & Alena. Natural Selection. Individuals in a population have different characteristics based on their heritable traits Those with the most favorable traits survive more frequently to pass on these traits to their offspring. Natural Selection.
