Biol 201: 1-14-2010 Darwin’ Theory: Individuals vary in traits and the variable traits are inheritable. However, he did not know how this inheritance happened. The idea way back is that genes are blended, which means that the children got ½ stuff from each parents and thus they are blended of their parents. However, this means that over time all the progeny become same and this was a problem for Darwin and his theory Mendilian Genetics: o Locus: physical location on a chromosome (at this location we find a specific gene) o Gene: A region of DNA, which codes for protein that has a function o Allele: alternative state, or different form, at a particular locus o Dominant: masks recessive o Recessive: gets masked by recessive o Two Theories: Genetic variation is maintained, which means that sometimes when blue and blue parents mate, they can give white children. Genetic variation is the heritable component of phenotypic variation. Mutations:
