Principle of independent assortment

codominance

-both alleles contribute to the phenotype -heterozygous is not a blend but a mix of colors

multiple alleles

-genes controlled by more than two alleles -individuals cannot have more than two alleles more than 2 possibilities can exist in the population

Incomplete dominance

-one allele is not completely dominant over another -heterozygous phenotype is between the two homozygous phenotype

What happens during the formation of gametes?

Genes segregate independently. EX: seed shape is separate from seed color

Mendel's point 4

alleles usually segregate independently. this means that traits separating doesn't depend on other traits separating

Mendel's point 1

genes are passed from parents to offspring

Mendel's point 3

genes are segregated during gamete formation

polygenic traits

trait controlled by 2 or more genes examples are human eye color and skin color

Mendel's point 2

when 2 or more alleles for single trait exist, some may be dominant and recessive
