1 Genetics Crosses Ch. 9.2 (p.174-178)
Monohybrid cross = genetic cross of one trait Predicted by simple Punnet square

3 Genetics Crosses Ch. 9.2 (p.174-178)
Complete dominance = one allele is completely dominant over the other Incomplete dominance = 2 or more alleles influence the phenotype Codominance = both alleles are expressed in a heterozygous offspring

5 Genetics Crosses Ch. 9.2 (p.174-178)
Dihybrid cross = cross between individual parents involving two independent traits Make a 16 square Punnet Give each column/row one allele for each trait to get the 4 possibilities. (if easier split the traits) Follow alleles to fill in the Punnet squares How do we write the Punnet square?
