  • 0% Calico Male kittens
  • 25% Calico female kittens, XBXR

Explanation:

<u>Available data:</u>

  • The gene for Calico (multicolored) cats is an x-linked trait and codominant
  • Calico Females receive a "B" and an "R" gene, and have black and orange splotches on white coats. Their genotype is XBXR.
  • Males can only be black or orange, but never calico. Their genotype is XBY and XRY

                    Y      XBY      XRY  

F1) Among the whole progeny:

  •     2/4 = 50%  will be black (female XBXB and male XBY)
  •     1/4  = 25% will be Calico (female XBXR)
  •     1/4  = 25% will be Orange (male XRY)  

   Among females:

  •    1/2 = 50% of females will be black, XBXB
  •    1/2 = 50% of females will be Calico, XBXR
