Inheritance review

How are incomplete dominance and co-dominance different than a normal dominant / recessive pattern of inheritance?

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

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

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

A breed of chicken shows co-dominance 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

The genotype of:  bb   will have the PHENOTYPE of...

• black fur
• white fur
• course hair
• fine hair
