Test Cross
A cross between an individual with a dominant trait and a homozygous recessive individual. Shows genotype of dominant individual.
Monohybrid Cross
Cross between two heterozygous individuals, shows which allele is dominant. Ratio will be 3:1 if one is dominant
Dihybrid Cross
Cross between two individuals that are heterozygous for two different traits, shows dominant allele. Ratio will be 9:3:3:1 for dominant

A gene that affects multiple traits
When part of a chromosome breaks off and attaches to another
When either sister chromatids or homologs don't seperate
When there are too many or too few chromosomes
