Homozygous

Having two identical alleles for a trait, like both blue eye alleles.

Study Notes

Quarter 2 - Genetics

  • Alleles are different forms of a gene
  • Heterozygous describes an organism with two different alleles for a particular gene
  • Homozygous describes an organism with two identical alleles for a particular gene
  • Codominance occurs when both alleles of a gene are expressed fully in the phenotype
  • Incomplete dominance occurs when the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes
  • Haploid cells have a single set of chromosomes
  • Diploid cells have two sets of chromosomes
  • Students must create a Punnett square that includes genotype, phenotype, ratios, and probability
  • A pedigree must be included, properly labeled, shaded, and include 3 generations, along with the Punnett squares
