Inheritance Patterns

Two traits are blended or create a "new" trait

• complete dominance
• incomplete dominance
• codominance

A man with crooked teeth marries a woman with straight teeth. Most of the their children have straight teeth.

• complete dominance
• incomplete dominance
• codominance

How many alleles does an individual have for each trait?

• 1
• 2
• 3
• 4

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

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

A calico cat shows both the traits for orange fur and black fur. What kind of allele expression is this?

• Incomplete Dominance
• Co dominance
• Independent assortment
• Recessive inheritance

A roan cow shows co-dominance in fur color (orange and white). What is the phenotype ratio expected if a roan cow and a roan steer mate together?

• 4: Orange and White
• 1: Orange : 1 White
• 2 Orange: 2 Orange and White: 0 White
• 1: Orange: 2 Orange and White: 1 White

How are Incomplete Dominance and Co Dominance different than a normal Mendelian cross?

• There is no difference
• The heterozygous genotype has a unique phenotype
• There is no heterozygous genotype
• There is only one phenotype regardless of genotype.

A breed of chicken shows codominance for feather color. One allele codes for black feathers, another codes for white feathers. The feathers of heterozygous chickens of this breed will be:

• all black
• all white
• all gray
• speckled black and white
