- Carbon Copy (CC), the first cat produced from aclone, was created from an ovarian cell taken from hergenetic donor, Rainbow, a calico cat. The diploid nucleusfrom the cell was extracted and then injected into an enucleatedegg. The resulting zygote was then allowed to developin a petri dish, and the cloned embryo was implanted inthe uterus of a surrogate mother cat, who gave birth to CC.CC’s surrogate mother was a tabby (see the photo below).Geneticists were very interested in the outcome of cloninga calico cat because they were not certain if the cloned catwould have patches of orange and black, just orange, orjust black. Taking into account the Lyon hypothesis, explainthe basis of the uncertainty. Would you expect CC to appearidentical to Rainbow? Explain why or why not.The plant Haplopappus gracilis has a 2n of 4. A diploid cellculture was established and, at premitotic S phase, aradioactive nucleotide was added and was incorporatedinto newly synthesized DNA. The cells were then removed from the radioactivity, washed, and allowed to proceed through mitosis. Radioactive chromosomes or chromatids can be detected by placing photographic emulsionon the cells; radioactive chromosomes or chromatids appeared covered with spots of silver from the emulsion.(The chromosomes “take their own photograph.”) Drawthe chromosomes at prophase and telophase of the firstand second mitotic divisions after the radioactive treatment. If they are radioactive, show it in your diagram. Ifthere are several possibilities, show them, too.Which of the following includes all of the others? a. homeotic genes c. SRY gene b. master genes d.

O Each coat color is the result of mutations that take place after the horse is born. The recombination of genes during meiosis results in offspring that exhibit a variety of coat colors. O Varying gene expression after fertilization leads to a variety of coat colors. O Recombination during mitosis leads to the expression of different coat colors as the horse develops.
