Genetics

The Law of Segregation Paired alleles separate during the formation of gametes

Law of Independent Assortment Factors separate independently of one another during the formation of gametes

Incomplete Dominance Neither allele is completely dominant over the other

Codominance Both alleles are expressed

Dihybrid crosses 2 traits are tracked Find genotype for parents example- predicting for seed texture & seed color Find genotype for parents Create possible gametes using FOIL Using a punnett square to determine possible offspring Cross RRYY with rryy

Brown eyes & brown hair are both dominant A blonde, blue eye girl crosses with a homozygous brown hair & brown-eyed boy. What are the genotypic & phenotypic ratios?

Brown eyes & brown hair are both dominant A heterozygous boy crosses with a heterozygous girl-what are the genotypic and phenotypic ratios?

Brown eyes & brown hair are both dominant A homozygous dominant for both traits crosses with a heterozygous dominant for hair and a homozygous recessive for eyes. What are the ratios?
