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.

When more than two versions of a gene for a particular trait exist in the human population, it is a ____________________ trait.

• sex-linked

• polygenic

• epistatic

• multiple allele

A roan cow shows codominance in fur color (brown and white). What is the phenotype ratio expected in offspring a female roan and a male roan mate together?

• All four would be brown and White

• Half would be orange, half would be white

• 2 Brown: 2 Brown and White: 0 White

• 1 Brown: 2 Brown and White: 1 White
