On an island with no large predators, some ducks are born with a mutation that gives them stubby little wings. These ducks can’t fly, but there’s really no need to fly since there are no predators. In fact, they have an advantage because they don’t have to eat as much to support those big wings like the other ducks. Over time, the flightless ducks reproduce better than the regular ducks, and eventually all the regular ducks die out. What characteristic of life is being demonstrated here? Group of answer choices

Suppose that a single gene has been shown to influence 3 different characters: Number of cholesterol receptors on cells, lung capacity, and blood volume in heart chambers. This is an example of what genetic effect?

In the cancer gene detection lab, a restriction enzyme is added to the p53 genes taken from different locations in the person's body; this restriction enzyme cuts at the location of the mutation (if there is one present). When the enzyme is added to the p53 genes from the tumor, this will result in ____ fragments, and _____ bands on an electrophoresis gel when the DNA fragments separate out.

which of the following is peto's paradox? o despite having more cells ( and therefore more genome replications), large mammals like whales and elephants rarely get cancer. o naked mole rates rarely get cancer. o tardigrades are able to withstand radiation doses that would normally induce mautations and cause cancer in other organisms. o despite have a short lifespan ( and rapid reproduction period), rabbits rarely get cancer.

Voles that are born in the Spring have thin coats as adults, while voles that are born in the Fall have thick coats as adults. Most voles live only a few months; voles born in the Spring are alive during the warm summer season, while voles born in the Fall are alive during the cold winter season. The environment experienced by the mother during pregnancy determines coat thickness in the offspring. Now consider a situation in which the environment the vole mothers during pregnancy changes, such that voles born in the Fall now have thin coats. Assume in this case that the Winters are still cold. This scenario provides an example of which of the following hypotheses?   a.Environment mismatch hypothesis  b.Endocrine disruptor hypothesis c.Thrifty genotype hypothesis d.Plasticity first hypothesis

What can happen when DNA is injected into the nucleus of an animal’s egg cell?

Scientists have cloned some animals by injecting a nucleus from an early embryo into an enucleated egg cell. Does this outcome demonstrate that genetic material is not lost during development? Why or why not?

The idea that sperm carry more mutations thanoocytes makes sense. Explain how?

Imagine you are studying fruit flies with a mutation. During the lab experiments, it was discovered that the mutation is determined by a dominant allele. From the 100 fruit flies collected, 76 of them carry the mutation.  Find the frequencey of the mutation and in words elaborate what did you assume to get this answer?
