Post by: evaaaaa on Mar 31, 2018
In the Bombay phenotype, a gene in the
  recessive condition blocks the expression of A
  and B red blood cell antigens. Thus, all A, B,
  and AB genotypes are expressed as the O
  phenotype. This is an example of
 
  a. complete dominance.
  b. epistasis.
  c. incomplete dominance.
  d. co-dominance.
  e. pleiotropy.

Question 2

In cows, certain coat colors are co-dominant.
  For example red is dominant; white is
  recessive; roan (red and white) is co-dominant.
  If a roan bull is crossed with a white cow what
  will be the expected coat colors of the calves?
 
  a. all roan
  b. half roan and half white
  c. half red and half white
  d. 3/4 roan and 1/4 white
  e. 1/2 roan, 1/4 red, 1/4 white
