Why is it easier for researchers to study the genetic contribution to disease in the population of Finland or Iceland as opposed to that of the UnitedStates?

Which of the following statements about recombination frequency is accurate? Recombination frequency is the physical distance between genes in units of base pairs. Recombination frequency is calculated by comparing the mutation rates of two organisms. Recombination frequency is the defining characteristic of an organism's mutation rate. O Recombination frequency is lower when genes are closer together.

Why might scientist point out the potentially hindering role that volunteer bias might play in the master and johson finding?

It is clear that patterns of genetic variation among populations can affect both disease risk and treatment efficacy and safety. Yet, a majority of studies still occur in European ancestry populations and the results can have limited utility across populations. Do you have any suggestions or plans to solve these problems

How does Mutation and Migration fit within the scope of Population Genetics?

If 9% of an African population is born with a severe form of sickle-cell anemia (ss), what percentage of the population will be more resistant to malaria because they are heterozygous (Ss) for the sickle-cell gene? Assume Hardy-Weinberg conditions. Submit your answer as it is. a) homozygous recessive individuals (q²) b) the recessive allele (q) c) the dominant allele (p) d) homozygous dominant individuals (p²) e) heterozygous individuals (2pq)

Heterosis is a) the appearance of spontaneous mutations. b) a method of artificial breeding that reduces heterozygosity. c) caused by inbreeding. d) when offspring have a phenotypic improvement over their parents.

What impact might a vaccine against malaria have on the frequency of the Sickle Cell allele in Africa in the long run?

Gene flow can have one effect in the context of a single population, and a different effect in the context of two populations that were recently isolated from one another. Describe with specificity the effect that gene flow has a) on a single population, as well as b) on two populations that were recently isolated from one another.

Recently, scientists have identified a mutation that is found at high frequency in Finnish populations, located in northern Europe where the winter is very cold.  This mutation is believed to be a “cold sensitive” allele that warns people of extreme cold temperatures. Could this allele have undergone a “selective sweep”, if it had suddenly appeared in this northern population of humans? How would such a selective sweep be detected with genome data?
