Presentation Transcript

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

  2. Genetics CrossesCh. 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

  3. Genetics CrossesCh. 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?
