BIOL 1204 Study Guide - Midterm Guide: Homologous Chromosome, Genetic Drift, Heritability
Document Summary
Biol 1204 midterm i study guide (excluding hardy-weinberg, breeder and heritability equations) Adaptive radiation: a sequence of multiple speciation events resulting from natural selection originating from a common ancestor. Allele: a variation that arose from a mutation and exist at the same locus on homologous chromosomes. Fixation: the change in a gene pool from a situation where there are at least two variants of an allele to a situation where only one of the alleles remain. Gene: the physical and functional part of dna. Gene flow: the movement of alleles within populations. Genetic drift: a change in the gene pool of a population due to chance. Genotype: the underlying genetic makeup of an organism or of a phenotype. Heritability: is the fraction of the total phenotypic variation in a population that is caused by genetic differences among individuals. Hybridization: when very divergent species (two species that share a common ancestor millions of years ago) can mate and produce offspring.
