Non Mendelian Genetics and Dihybrid Crosses

Produces gametes called sperm or pollen

• Male

• Female

• Somatic

• Allele

Produces gametes called eggs or ova

• Male

• Female

• Stem Cells

• Somatic

Traits that come from more than one set of alleles. The trait for height in humans comes from at least

3 genes and 6 alleles.

• Monohybrid Crosses

• Polygenetic Traits

• Incomplete Dominance

• Complete Dominance

Traits that come from environmental exposure (like accidents). These are not passed on to offspring.

• Monhybrid Traits

• Inherited Traits

• Polygenetic Traits

• Acquired Traits
