Document Summary

Darwin suggested these mechanisms happen because of natural selection. Which requires all individuals that have reproductive advantage will result in magnification of these traits in population. When trait results in reproductive advantage it"s called adaptation. Intersexual selection choosing mate based on traits. Intrasexual selection members of same sex compete for partners of opposite sex. Original theory of evolution is called the historical theory of evolution. Modern synthesis is what we refer to the current version of evolution. It is based on what we know about genes, dna, chromosomes and population biology. We have 23 pairs of chromosomes, we have about 26000 to 40000 genes. Genotype is your genetic composition and is invariant during lifetime. Only genotype is passed on to children. Genes don"t make traits, they make proteins. More than one form of a given gene alleles. There is allele for different characteristic that makes protein. Phenotype is your genotype and environment interaction. for it.
