n hamsters the gene for black/white fur color is on the X chromosome. The dominant allele produces black fur and the recessive allele produces white fur. Oreo is a female hamster with patches of black and white fur.   Part 1   Oreo mates with Vanilla, a white, male hamster.  Of their female offspring, Question Blank 1 of 3 will have all black fur, Question Blank 2 of 3 (on average) will have all white fur, and Question Blank 3 of 3 (on average) will have patches of black and white fur. Part b In observing the state of the Xist promoter sequence in Oreo's cells, which of the following is true? Part 2   In observing the state of the Xist promoter sequence in Oreo's cells, which of the following is true? In black fur cells, the Xist promoter is methylated on both chromosomes. In white fur cells, the Xist promoter is methylated on both chromosomes. In white fur cells, the Xist promoter is methylated on the chromosome that contains the allele for the black coat color. In white fur cells, the Xist promoter is methylated on the chromosome that contains the allele for the white coat color.
