Question

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. Cats that have coats that are a patchwork of black and orange are called tortoiseshell cats, are typically female, and have genes that code for both black fur (Xo) and orange fur (XO) located on the X chromosomes. Y chromosomes do not code for color in tortoiseshell cats. A female cat that has only orange fur (XOXO) is crossed with a male cat that has only black fur (XoY). How many of the offspring will exhibit tortoiseshell coloring? 1 in 4. 2 in 4. 3 in 4. 4 in 4.

Answer 1

2 in 4

Step-by-step explanation:

If a female cat with orange fur (XOXO) is crossed with a male cat with black fur (XoY) then:

P: XOXO x XoY

F1: XOXo XOY XOXo XOY

This means that half of the offspring will be females with tortoiseshell color (XOXo) and other half of the offspring will be males with orange fur (XOY).
