This Concept Map, created with IHMC CmapTools, has information related to: Evolution of Populations- Group 3, Individuals that are heterozygose genotype have a greater fitness than do homozygose geneotypes Example One copy results in a carrier of sickle cell and resistance to malaria. Two copies result in sickle cell deseas, mate choice Example A female peacock chooses a male peacock who is "the prettiest", Individuals & alleles traveling between populations caused by natural disaster/change of events Example An animal from one herd mating with another herd, Changes in nucleotide sequences that cause new genes and alleles to arise Examples Only mutations in cells that produce gametes can be passed to offspring, Natural Selection ???? Heterozygote Adavantage, The Founder Effect Definition When a few individuals become isolated froma larger population, Heterozygote Adavantage Definition Individuals that are heterozygose genotype have a greater fitness than do homozygose geneotypes, New alleles that are selected for Definition Changes in nucleotide sequences that cause new genes and alleles to arise, One copy results in a carrier of sickle cell and resistance to malaria. Two copies result in sickle cell deseas ???? Mutation in hemaglobin results in sickle cell deseas, Sexual Selection Leads to sexual dimorphism Intrasexual Selection, The Bottleneck ???? results in lost of alleles & reduction in gentic variation, Evolution of Populations Populations evolve by Gene Flow, Natural Selection ???? Balancing Selection, Intrasexual Selection Definition Competition among one sex, Adaptive evolution Definition evolution that results in a better match b/w organisms & environment, Alleles get modified in unpredictable ways by three mechanisms. ???? The Bottleneck, Changes in nucleotide sequences that cause new genes and alleles to arise Examples Mutation in hemaglobin results in sickle cell deseas, Alleles get modified in unpredictable ways by three mechanisms. ???? The Founder Effect, Evolution of Populations Populations evolve by Genetic Drift, Individuals have inherited traits picked by several factors that lead to ???? Adaptive evolution
