Question

In mice, albinism (g) is recessive to grey coat colour (G). A grey mouse mated with an albino mouse. Over the course of several months, 38 pups were born. Out of 38 pups, 17 had a grey coat, and 21 were albino.

Theoretically, what is the expected result from the parental cross of a grey mouse and an albino mouse, and why does the expected result not match the result stated in the information given above?

a. Theoretically, there should be a 3:1 ratio of grey mice to albino mice, or 29 grey coat mice and 9 albino mice. With more litters, the actual results would match the expected results more closely.

b. Theoretically, there should be a 1:1 ratio of grey mice to albino mice, or 19 grey coat mice and 19 albino mice. With more litters, the actual results would match the expected results more closely.

c. Theoretically, 100% of the mice should have grey coats so all 38 offspring should have grey coats. There was an experimental error that can account for the deviation.

d. Theoretically, there should be a 3:1 ratio of grey mice to albino mice, or 28.5 grey coat mice and 9.5 albino mice. There was an experimental error that can account for the deviation.
