Objectives: 

  • Distinguish among observed inheritance patterns caused by several types of genetic traits (dominant, recessive, codominant, sex-linked, polygenic, incomplete dominance, multiple alleles).
  • Describe how Mendel’s laws of segregation and independent assortment can be observed through patterns of inheritance (e.g., dihybrid crosses).
  • Use a Punnett Square to determine the probabilities for genotype and phenotype combinations in monohybrid crosses.
