A black female cat is mated with an orange male cat. They produce two tortoiseshell females, two black males, one orange female, and one tortoiseshell male, for a total of six kittens. Orange and black fur color are encoded by different alleles of the same X-linked fur color gene. Based on the phenotypes of the parents, what sex chromosomes do the orange female and the tortie male offspring have?

1- The orange female is missing one X chromosome, and the tortoiseshell male is XXY.

2-The orange female has more than one X chromosome, and the tortoiseshell male is XXY.

3-The orange female is missing one X chromosome, and the tortoiseshell male is YO. 4-The orange female is XX, and the tortoiseshell male is YO.

Select the most likely explanations for the sex chromosome types:

1- The male tortoiseshell received a black X chromosome from his mother and no color genes from his father.

2-When only one X chromosome is present in the female, it does not become inactivated.

3-The X chromosomes in the male tortoiseshell are randomly inactivated. 4-The orange female has two X chromosomes, and the black X from her mother is inactivated.
