Patterns of Inheritance

A pattern of inheritance in which a trait is carried on one of the sex-determining chromosomes.

• Dominant Inheritance
• Co-dominance
• Incomplete dominance
• Sex-linked inheritance

What type of inheritance do two alleles have if their traits blend together? 

• Incomplete Dominance
• Co-Dominance
• Dominant / Recessive Inheritance
• Homozygous Inheritance

• Incomplete Dominance
• Co-dominance
• Sex-linked inheritance
• Recessive inheritance

This type of inheritance pattern shows BOTH traits in possible offspring

• complete dominance
• incomplete dominance
• co-dominance
• dominant pattern

When genes with three or more alleles control traits

• incomplete dominance
• polygenic
• co-dominant
• multiple alleles

Incomplete dominance results in _______

• Full expression of both alleles
• A blend of the two alleles.
• Expression of the more dominant trait
• Expression of the more recessive trait

If there are 2 alleles for a trait, and one has the ability to totally "cover up" the other, the one that can be "covered up" is called ________.

• Dominant

• Recessive

• Primary

• Genetic

• Incomplete Dominance
• Codominance
• Pleiotropy
• Simple Mendelian Inheritance
