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

When many genes influence a trait we referred to this as

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

Which of the following can also affect traits expression

• color
• size
• height
• environment
