Document Summary
Gregor mendel- austrian monk whose breeding experiments with peas shed light on the riles of inheritance (1822-1884) Mendel was a contemporary of darwin, but his work was overlooked until the 20th century. Mendel and darwin lived at the same time but their work didn"t mix. The modern synthesis (early 1940s)- a conceptual synthesis of darwinian evolution, mendelian inheritance, and modern population genetics. Phenotype- physical appearance/all expressed traits of an organism. Genotype- genes that make up phenotype/the entire genetic makeup of an individual (its genome, which is its full complement of genes and the two alleles that comprise each locus), or a subset of an individual"s genes. Homozygous recessive- rr evolution- a change in allele frequency in a population (a change in the gene pool) Population- all of the individuals of a species in a given area. Population genetics- examines the frequent, distribution, and inheritance of alleles within a population.
