Draw a hypothetical biochemical pathway | Homework Help

Suppose that in your lab you occasionally get mice that have some sort of bizarre mutation-bent ears. You determine that the bent-ear trait is recessive. You then find out that someone else in your lab has isolated mice with bent ears as well and that they have also determined that bent ears are a recessive trait.

Imagine that you cross one of your bent-eared mice with one of your lab mate’s. The results yield something other than bent-eared mice-all normal ears. The ratio you get from the crossing the F1 is 9:7 (normal to bent).

a) How do you explain these findings?

b) Draw a hypothetical biochemical pathway that would explain these findings.

c) What is this phenomena called?
