Choose the correct GENE FORMULA for each of the following locations on the Punnett Square.

If the female is heterozygous, she's going to have the genotype CcDd.

is this question correct? or what did you get for an answer?

Is this right Bio_man? The answer is incomplete

I'm unsure how to answer this because a female is CcDd

So her alleles would be:

   C   c
D   CD   cD
d   Cd   cd

I know the top represents the female

In a test cross, the test subject is always recessive for both traits so that you can determine the which dominant traits are in the other animal being crossed (the female in this case).

So the male would have a genotype of ccdd.

The first row of alleles on the male side is cd because a purnett's square always starts with the first letter of the first genotype and the first letter of the second genotype. That's why the female's first allele on the graph is CD, because in her genotype, CcDd, C is the first letter of her Cc gene and D is the first letter of her Dd genotype. 

The second allele on the graph for the female labelled alleles 1 would be Cd, as a purnett's square uses the first letter of the first genotype and the second letter of the second genotype in the second row.

Genotype three would be a cross between cd and cD which would result in a genotype of ccDd.

As a result, the number combination is:
Alleles 1 = 3
Alleles 2 = 1
Genotype 3 = 9
Test cross male parent: = 7
