- The Human Genome Project has demonstrated that in humans of all races and nationalities approximately 99.9 percent of the sequence is the same, yet different individuals can be identified by DNA fingerprinting techniques. What is one primary variation in the human genome that can be used to distinguish different individuals? Briefly explain your answer.Albinism in humans can be caused by mutations in any one of several different genes. This situation, in which the same phenotype may result from variation in several different genes, is referred to as genetic heterogeneity. Is genetic heterogeneity common? Are most genetic traits in humans the result of variation in a single gene, or are there many genetic traits that result from variation in several genes, as albinism does?Which of the following statements best characterizes genetic diversity in humans? 1.) There are far more genetic differences between populations/groups than there is variation within populations. 2.) Between-group differences in most phenotypic traits (e.g., athletic ability, performance on standardized tests, etc.) are mostly inherited and due to the effects of natural selection. 3.) The vast majority of polymorphisms (such as SNPs) in the genome are informative about a person's ancestry (in other words, you could get a pretty good idea of someone's ancestry by looking at their genotype at just about any random SNP in the genome). 4.) Humans have much lower levels of genetic diversity than most other animals.
- The dog breed West Highland Terrier is a product of artificial selection. Give a brief description of the breed and its desired traits. What wild ancestor did it come from? Was it produced with selective breeding or genetic engineering (i.e. genetically modified)? What are the benefits of artificial selection in this case? Are there potential negative consequences?Geneticists study mitochondrial and Y-chromosome DNA to determine the ancestry of modern humans. Such studies have led to the emergence of mitochondrial Eve and Y-chromosome Adam, whose features above are a far-cry from an artist's interpretation of the Biblical narrative. Their progeny came to have the range of physical features now described as racial differences. How has modern genomics contributed to the debate about the validity and definition of these hypothetical parents and their descendants? References:One of the original Amish colonies rose from a ship of colonists that came from Europe. The ship’s captain, who had polydactyly, a rare dominant trait, was one of the original colonists. Today, we see a much higher frequency of polydactyly in the Amish population. This is an example of what and why you think so?
- The MC1R gene affects skin and hair color in humans.There are at least 13 polymorphisms of the gene inEuropean and Asian populations, 10 of which are nonsynonymous. In Africans, there are at least 5 polymorphisms of the gene, none of which are nonsynonymous.What might be one explanation for the differences inMC1R variation between Africans and non-Africans?The agouti gene determines coat colour in mice. Heterozygous mice have yellow coats, while homozygous dominant mice have black coats. However, having two copies of the recessive alleles is lethal. In a population of 2 000 mice, 1 082 mice have black coats. a) Calculate the frequency of each allele. Show all your work and express your answer as a value between 0 and 1 rounded to two decimal places. b) What percentage of the mouse population is expected to be carriers of the lethal allele? Show all your work and express your answer rounded to one decimal place. c) How many mice will die during fetal development? Show all your work and round your answer to the closest whole number.The original source of all genetic variation is what?
- 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.)What is the genetic basis for human variation?The eugenic movement was created in the early 20th century by Sir Francis Galton. Its aim was to improve the genetic pool of the human population by selective breeding. One idea was to discourage individuals with Mendelian autosomal recessive diseases to have children. However, the fallacy of this idea is shown by the fact that recessive lethal alleles (that are never found in homozygosity) can persist in populations for hundreds to thousands of generations. Which one of the following statements best explains the persistence of those alleles in populations? There is heterozygote advantage in those populations. Recessive alleles keep being produced by mutation. Recessive alleles cannot be selected against when present in heterozygotes. Genetic drift keeps recessive alleles at a relative high frequency in populations. Consider the action of mutation and of genetic drift in a population. What do you expect genetic variation will be in a…
