Genetics
2
The Law of Segregation Paired alleles separate during the formation of gametes
4
Law of Independent Assortment
Factors separate independently of one another during the formation of gametes
7
Incomplete Dominance Neither allele is completely dominant over the other
9
Codominance Both alleles are expressed
11
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
12
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?
13
Brown eyes & brown hair are both dominant
A heterozygous boy crosses with a heterozygous girl-what are the genotypic and phenotypic ratios?
14
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?
