Coat color in cats is a codominant trait and is also located on the X chromosome. Cats can be black, orange or calico. A calico
cat has black and orange splotches. In order to be calico. the cat must have an allele for the black color and an allele for the orange color. Use a punnett square to show why there are no male calico cats.
There can be no male calico because for an offspring to be a calico the two codominant alleles must each be carried on the two X chromosomes and in the males, there is the presence of just one X chromosomes, thus they can either be black or be orange. For the females, the can only be black if they carry the black allele on both X chromosomes, the same goes for the orange.
I’m unsure how to answer this because I don’t know How much bacteria there was What bacteria it was And what the conditions of the bacteria are This chart is from Dr. Jason from the math forum http://mathforum.org/library/drmath/view/64555.html hope this helps!
