Why might some light-skinned populations, such as the Japanese, be missing the F374 allele for lighter skin pigmentation? (Hint: Consider the various forces of evolution that may be at play.)
Which of the following is not true of the sickle-cell allele? a)it became an important genetic factor after slash-and-burn agriculture was introduced b)it became an important genetic factor after fields were cleared that put humans near mosquitos c)it became an important genetic factor approximately 2000 years ago d)it provides a reproductive advantage to heterozygotes e)only homozygous normals will survive thanks to this trait
Looking to the future, what changes to the frequency of the sickle-cell allele do you envision as most likely, and why? (In other words, do you envision it becoming more common or less common in human populations?) What factors (technology, climate change, etc) might be driving those changes?
If allele frequencies in the hemoglobin gene are influenced by sickle cell anemia on the one hand and by resistance to malaria on the other hand, what factors may cause a change in these allele frequencies over time?
Using the HardyWeinberg Law in Human Genetics Suppose you are monitoring the allelic and genotypic frequencies of the MN blood group locus (see Question 2 for a description of the MN blood group) in a small human population. You find that for 1-year-old children, the genotypic frequencies are MM = 0.25, MN = 0.5, and NN = 0.25, whereas the genotypic frequencies for adults are MM = 0.3, MN = 0.4, and NN = 0.3. a. Compute the M and N allele frequencies for 1-year-olds and adults. b. Are the allele frequencies in equilibrium in this population? c. Are the genotypic frequencies in equilibrium?
Consider Mendelian traits versus polygenic traits. What impact do modifications, such as those offered by CRISPR and genetic testing, have on the generational lineage of these traits?Are some traits (e.g., susceptibility to Sickle Cell Anemia) worth removing from our genome? Support your position.
You are examining a population of snakes in which 20% of the individuals exhibit the recessive phenotype for albinism. If albinism is exhibited only by the genotype aa, how many snakes out of a population of 100 would you expect to CARRY the albinism allele (so be Aa), but be normal color?
What evolutionary factors can cause allele frequencies to change and possibly lead to a genetic polymorphism? Discuss the relative importance of each type of process.
The allele for sickle anemia is found at higher frequencies in central Africa than in other parts of the world. What are the advantage and disadvantages?
Tay-Sachs disease is a recessive genetic disease. Individuals with this disease rarely survive past the age of four. In the general population, approximately 1 person in 300 carries the allele for this disease. However, in some populations, including the Irish Americans, the Ashkenazi Jews and the Cajuns from Louisiana, the proportion of Tay-Sachs carriers is much higher (1 in 27 to 1 in 50) than in other populations. Which evolutionary scenario can be predicted to produce a high frequency of Tay-Sachs disease in these populations? Select one: a. All three populations descend from a small number of settlers b. The Tay-Sachs allele is advantageous at the heterozygous state c. These populations experienced disruptive selection d. These populations experienced stabilizing selection e. These populations have higher than average mutation rates
Identify each of the following as an example of allele, genotype, and/or phenotype frequency: A. Approximately 1 in 2500 people of Northern European descent is born with cystic fibrosis. B. The percentage of carriers of the sickle cell allele in West Africa is approximately 13%. C. The number of new mutations for achondroplasia, a genetic disorder, is approximately 5 × 10–5.
