Answer:

The correct answer is - XTXt

Explanation:

In the question, it is given that in cats the coat color is an X-linked trait that shows incomplete dominance if present in heterozygous condition.

The allele for yellow allele = XT (it is dominant allele)

The allele for black coat = Xt (it is recessive allele)

The amle cat can not show the heterozygous condition or tortoise coat as they have only one X chromosome so they will be either yellow coat cats or black coat cats.

In female cats the tortoise coat will show when the both allele present together: XTXt due to their incomplete dominance.
