The trait expressed if only one allele is present is the ___ allele

• Dominant
• Recessive
• Genotype
• Exterior

If a T represents an allele and a t represents the other possible allele what is t representing?

• Dominant trait
• Recessive Trait
• Sex Linked Trait
• Limited expression in the population

Crossing a pea plant with green peas and a pea plant with yellow peas is an example of a(n)

• dihybrid cross
• incomplete dominant trait
• monohybrid cross
• a cross with multiple alleles

A dog with blue eyes and black hair is bred with a dog with brown eyes and yellow fur. The resulting dogs are all brown eyed and black furred. This is an example of 

• a dihybrid cross
• a monohybrid cross

This is an example of ___________?

• Incomplete dominance
• Co-Dominance

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

• Co-Dominance

• Mendelian Inheritance (Complete Dominance)

• Homozygous Inheritance

The different forms of a gene are called

• traits
