Textbook Question
Chapter 7, Problem 3NST
Carbon Copy (CC), the first car produced from a clone, was created from an ovarian cell taken from her generic donor, Rainbow, a calico car. The diploid nucleus from the cell was extracted and then injected into an enucleated egg. The resulting zygote was then allowed to develop in a petri dish, and the cloned embryo was implanted in the 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 cloning a calico cat because they were not certain if the cloned cat would have patches of orange and black, just orange, or just black. Taking into account the Lyon hypothesis, explain the basis of the uncertainty. Would you expect CC to appear identical to Rainbow? Explain why or why not.

Background Info
Rainbow trout go through a unique genetic reproductive process. Female eggs are diploid, while male sperm are haploid. In the wild, when the sperm fertilizes an egg, the extra set of chromosomes is kicked out, resulting in a diploid offspring.Triploid trout are produced in the lab to provide sterile fish stock for lakes. Shortly after the eggs are fertilized, scientists place them in a warm water bath to prevent the extra chromosomes from being removed. The result is a triploid fish that cannot reproduce.Rainbow Trout: n = 30
Global warming is an issue affecting many species around the world. Warming has caused the temperatures in lakes and rivers to increase and stay elevated for longer periods of time.

What procedure could he use to obtain this information?

The upper extremities of the whale, the bat, the cat, the horse and the man, fulfill in some the function of fins to swim, in others the function of wings to fly, and legs or arms in the case of the man, but all of them maintain the same structure with the same number of bones. This allows us to identify a common ancestor in these groups. What evidence of evolution does the example refer to?
Group of answer choices

- Is it acceptable or not to edit the genome of human embryos to treat genetic diseases? There is a group of genetic disorders that cause fatal childhood diseases. To avoid having children with these genetic disorders, some parents choose to use a procedure called in vitro fertilization (IVF) followed by genetic testing. Typically, in the first step of IVF, women receive hormone injections to produce multiple eggs, after which the eggs are harvested. The eggs are then fertilized by sperm in a petri dish to make embryos, which are then transferred to a woman's uterus. If the goal is to identify embryos that do not have specific genetic conditions, doctors would screen the embryos before they are implanted into the woman - in other words, they would analyze the embryos' DNA to look for variants of the gene(s) that cause the genetic disorder. While the genetic testing of IVF-produced embryos has been done for decades, the procedure is controversial. The controversies include worries that…arrow_forwardA company that offers PGD terms an embryo “normal and healthy” if it has 46 chromosomes.

Sperm and egg cells are diploid, meaning that they have two copies of the human genome. Somatic cells are haploid, meaning that they have one copy of the human genome.

- In the past, the IOC has employed two genetic sex- determination tests. The Barr body test screens for the presence of two X chromosomes. In XX somatic cells, one copy of the X chromosome condenses into a largely inactive structure called a Barr body, which can be seen using a light microscope. In more recent years, a polymerase chain reaction-based screen has been used to amplify the DNA sequence of the SRY gene, which is found only on the Y chromosome. Based on their karyotypes, what would be the outcome of these two tests for each of the four individuals? Drag the labels to indicate the presence or absence of a Barr body and the SRY gene sequence.arrow_forwardWoolly mammoths have been extinct for about 10,000 years, but we often find their well- preserved remains in Siberian permafrost. Research groups are now planning to use SCNT to resurrect these huge elephant- like mammals. No mammoth eggs have been recovered so far, so elephant eggs would be used instead. An elephant would also be the surrogate mother for the resulting embryo. The researchers may try a modified SCNT technique used to clone a mouse that had been dead and frozen for sixteen years. Ice crystals that form during freezing break up cell membranes, so cells from the frozen mouse were in bad shape. Their DNA was transferred into donor mouse eggs, and cells from the resulting embryos were fused with mouse stem cells. Four healthy clones were born from the hybrid embryos. What are some of the pros and cons of cloning an extinct animal?arrow_forwardIn the reproductive cloning of an animal, what cell type is used as the source of the genome of the cloned animal?
