genetic problems involving two traits
dihybrid cross
when dom and res are present
incomplete dominence
together in hybrid there is a blending of traits
Intermediate inheritance
when more than 2 alleles determine a trait
Polygenic inheritence
genetic problems involving 3 traits
trihybrid cross
when there are more than 2 alleles for a trait (ex IA IB i)
multiple alleles
chromosomes that determine gender
sex determination
traits attached to a sex chromosome
sex linkage
