You cross a true breeding pink eyed, long nosed Shmoo to a pure breeding blue eyed, short nosed Shmoo. All of the offspring are blue eyed and long nosed. When you cross some of the F₁s you get the following results:

98 blue, long 42 blue, short 37 pink, long 13 pink, short

How many pink, short Shmoos would you expect?

You cross a true breeding pink eyed, long nosed Shmoo to a pure breeding blue eyed, short nosed Shmoo. All of the offspring are blue eyed and long nosed When you cross some of the F1s you get the following results: 98 blue, long 37 pink, long 13 pink, short 42 blue, short How many pink, short Shmoos would you expect? 35.625 106.875 47.5 11.875

Solution

Let us assume here that the ratio of four phenotypes in the population is 9:3:3:1

Now total number of observed frequencies = (98+42+37+13)=190

Thus expected frequency of short pink shmoos = 190*3/16 =35.625

Hence the correct answer is 35.625
