Question
Carbon Copy would have both black and orange patches on a black background (tortoiseshell cat).
ovarian cell used to clone her is XOXo because she is a calico cat. Recall that the X-linked O allele (orange) is dominant to the o allele (black). We will assume that for her autosomal gene that controls whether she is a calico cat or a tortoiseshell cat, Rainbow is SS (homozygous).
Make a prediction about the phenotype of Carbon Copy (Rainbow’s clone), if the following two things were true:
1) the ovarian cell from Cat has the X chromosome carrying the O(orange) allele inactivated
2) during the cloning process,when Cat's clone is developing as an embryo in the
surrogate mother, the X chromosomes DOES NOT undergo the normal X inactivation process (as if
the clone were developing from a newly fertilized egg).
Select the best prediction from the following six options:
1. Carbon Copy would have black patches only on a white background.
2. Carbon Copy would have black patches only on a black background.
3. Carbon Copy would have orange patches only on a white background.
4. Carbon Copy would have orange patches only on a black background.
5. Carbon Copy would have both black and orange patches on a white background (calico cat)
6. Carbon Copy would have both black and orange patches on a black background (tortoiseshell cat).
ALSO, How would it be possible to get:
Carbon Copy would have both black and orange patches on a black background (tortoiseshell cat).
Explanation / Answer
