Answer:
Step-by-step explanation:
(You posted this as a mathematical question. The biology department should have more fun with this kind of question. :) )
My uneducated guess would be that there is no real correlation between fur-colour and gender. Fur colour is associated with habitat circumstances: Having light fur makes the mice less visible on sand and dark fur does the same for rocky areas.
All you can produce from the given data are ratios:
A 42/14 ratio for male mice and a 33/11 ratio for females indicates,
that there are more male mice than female in rocky areas. We also observe, that there are generally more mice living in rocky areas than on sand and that the male to female-ratio in sandy areas is pretty much balanced.
