Independent Assortment The 2 Factor Cross: F1 RRYY x rryy What does it give us? The 2 Factor Cross: F2

Define Independent Assortment in your own words

Mendel’s Principles Genes are passed on from parents to their offspring In the case when there are 2 or more alleles for one gene, one may be dominant and one recessive Segregation of genes happens during meiosis The alleles that are segregated, segregate independently

Incomplete Dominance One allele is not completely dominant over another

Co dominance Both alleles contribute to the phenotype

Multiple alleles More than two alleles control a trait

Polygenic Traits Traits are controlled by 2 or more genes Eg. Eye color Skin color (4 genes)
