In the absence of evolution, the only way of producing new variation of single genes is gene flow.   Question 16 options:   A) True   B) False

Suppose that global warming causes ocean rise that obliterates most of the Gulf Coast of Florida and much of its human population, and that radiation leaking from the destroyed Big Bend Nuclear Power Station causes a mutation that yields green hair in humans with the homozygous recessive mutant allele. Many years pass and a new island appears in the Gulf. This island is then colonized by an intrepid human population that is fixed for the recessive green hair allele. If the island population grows to 10,000 individuals and then an individual who is heterozygous for the green hair locus arrives on the island and mates with one of the residents, how many generations will it take for the dominant, non-green hair allele to reach a frequency of 99%? (Assume viability selection 20% in favour of the non-green allele and ignore the effects of genetic drift).

Open-ended discussion type Question: Is sexual selection a type of natural selection? Why or why not?

Use the shapes below to answer Question number 2. Please be accurate and complete it CORRECTLY. Don’t use previous answers.

Read in the Introduction about the three kinds of natural selection: directional, stabilizing, and disruptive. In Procedure 9.1, the phenotype we are considering is size. Which one of these types of natural selection do you expect to see if your answer to question 1 above is correct? Explain.

A common and accurate definition of evolution is the change of an individual’s heritable trait. Question 6 a. True b. False

Usie the following textbook link to answer the question: (https://pressbooks.calstate.edu/explorationsbioanth2/chapter/2/) 1) In one paragraph, explain in your opinion, Why do you think the Theory of Evolution is so controversial? 2) In one paragraph, explain in your opinion, discuss your own ideas and also those presented in the 3 trials discussed in the textbook reading link

QUESTION 11 You are examining a new population that has recently migrated to and colonized a new island.  Which of the following characteristics would you expect to see in your population?   a. The new population will likely experience genetic drift related issues related to the founder effect.    b. The new population will suffer more the effects of mutation because this is a bottleneck event.   c. The new population will have high levels of heterozygosity and allelic richness.     d. The new population will most likely have the same allele frequencies as the original population.

Calculate the probability a new mutation, with one copy in the population, is lost by random genetic drift in the next generation for the following diploid populations: [a] N=5 [b] N=25 [c] N=1250
