Cat coat colour results from the interaction of three different genes. A gene for black-based colours is located on an autosomal chromosome. A gene for redbased colours is located on the X chromosome. A different gene located on a separate autosomal chromosome determines the pigment density in cat hair. The black-based gene has three possible alleles: B-black, b-chocolate, and b1 cinnamon. If pigmentation in cat hair is dense, the phenotypes listed below are possible. Use the following additional information to answer the next three questions There are two alleles for the pigment-density gene: dense pigment (D) and dilute pigment (d). The chart below shows the interaction of two autosomal genes affecting coat colour - the black-based gene and the density gene.

A blue-coloured female cat is bred with a cinnamon-coloured male cat. The offspring produced are black-coloured, blue-coloured, chocolate-coloured, and lilac-coloured. The genotypes of the parental cats are indicated in row

Using the list of percentages given above, record the phenotypic ratio with the appropriate numbers for the given expressions below? Your answer: Use the following additional information to answer the next question
In cats, red pigmentation is dominant to black pigmentation. The red pigment gene, which is located on the X chromosome, has two alleles: XR and Xr. Cats with at least one XR allele have some orange-coloured hair as a result of having the redbased pigment. Cats with only Xr alleles have no red-based pigment. Male cats with the XR allele will be orange. However, female cats express the genes on only one X chromosome in each cell. This expression is random. Therefore, an orangeand-black (tortoiseshell) female cat is possible if it is XRXr. Some genotypes and their resulting phenotypes are shown below. In all cases, pigment density is high. 8. The phenotype of a female cat with genotype XrX⊤Bb1 would be a black cat W an orange-and-black cat an-orange cat an orange, black, and cinnamon cat
