Question

When the cloned cat Carbon Copy (CC) was born (see the Now Solve This question in Section 7.4), she had black patches and white patches, but completely lacked any orange patches. The knowledgeable students of genetics were not surprised at this outcome. Starting with the somatic ovarian cell used as the source of the nucleus in the cloning process, explain how this outcome occurred.

Accepted Answer

Hey everyone, let's take a look at this question together, calico cats have at least three distinct colors in there, for which are most frequently white, Orange and black calico is controlled by a sex linked co dominant allele a female cat can have three types black, orange or calico, whereas male cats can be black or orange predict the correct ratio of kittens when a black male is crossed with an orange female. So we have our orange female and our black male. And so for black for we're going to use the L. E. O. B. And for orange we're gonna use the L. E. L. O. So when we cross these we have X. O. X. O. And we have X. B. And why? Because it is sex linked co dominant lille. So the Y chromosome does not get that. And so these are the results of that F. One cross. So we have X. B. X. O. And these are the calico cats because the combination of that black and orange alil leads to the calico cat. And so these are also calico females and we also have X. O. Y. And these are the orange mills. And so the calico females make up one half of the cross and the orange males also make up one half. And so that means we end up with 50% calico female and 50% orange male, which makes answer choice. C the correct answer because when we cross that orange female cat with that black male cat, we end up with 50% calico female and 50% orange males in the F one generation.
