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.

If you cross two checkered chickens (Bb x Bb), what would be the phenotypic ratio of the offspring?

• All Checkered
• 1 Black : 2 Checkered : 1 White
• 2 Black : 2 White
• 3 Black : 1 White

How can I test my blood group?

• By tasting

• By using antibodies

• By using antigens

• By mixing with the other blood groups

ABO blood grouping system is an example of

• incomplete domiance

• complete dominance

• codominance

• bad romance :)

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
