Polygenic Inheritance III. Human Genetics Fig Why peas?. Many pea varieties were available. 2. Small plants were easy to grow. 3. Peas self-fertilize. 4. Peas cross-fertilize. Traits used by Mendel had 2 Contrasting Forms

Parents transmit information about traits. Each individual receives two factors 2. Mendel s Principle of Segregation Gametes can only receive one of two alleles. 3. Mendel s Principle of Dominance One factor can be preferentially expressed 4. Not all factors are identical for a given trait. Alleles can be different Homozygous or Heterozygous combinations 5. Alleles do not influence each other. They remain discrete. They do not blend. 3

In a dihybrid cross, alleles of each gene assort independently. 2. Fate of one pair of alleles associated with one trait does not influence the fate of another pair of alleles associated with a different trait. 3. Genes located on different chromosomes assort independently.
