A pure-breeding white mouse with a long tail was crossed to pure-breeding pink mouse with a short tail. The F1 progeny were all pink with long tails. These F1 mice were test crossed to white mouse with a short tail.
If the gene controlling color and the gene controlling tail length in mice are very closely linked, what phenotypes are expected to be the most frequent in the progeny of the test cross?
Pink, short tail and white, long tail
There is not enough information to make a prediction.
Pink, short tail and white, short tail
Pink, long tail and white, short tail
Pink, long tail and white, long tail
