- Two pairs of genes (TTLL) are postulated to influence the size of corn in certain varieties with equal and additive effects. A tall corn variety averaging 6 feet was crossed with a dwarf corn variety averaging 2 feet. (a) If the size of the dwarf is attributed to the genotype (ttll), what is the effect of each gene that increases the size above 2 feet? (b) Diagram a cross between a large and small variety, and classify the expected F2 phenotypes.In a cross in Drosophila, a female heterozygous for the autosomallylinked genes a, b, c, d, and e (abcde/ + + + + +) was testcrossedwith a male homozygous for all recessive alleles (abcde/abcde).Even though the distance between each of the loci was at least3 map units, only four phenotypes were recovered, yielding thefollowing data: Phenotype No. of Flies+ + + + + 440a b c d e 460+ + + + e 48a b c d + 52 Total = 1000 Why are many expected crossover phenotypes missing? Can anyof these loci be mapped from the data given here? If so, determinemap distances.. If you intercrossed F1 heterozygotes of the formA b / a B in mice, the phenotypic ratio among the F2progeny would vary with the map distance betweenthe two genes. Is there a simple way to estimate themap distance based on the frequencies of the F2phenotypes, assuming rates of recombination areequal in males and females? Could you estimatemap distances in the same way if the mouse F1heterozygotes were A B / a b?
- A family pedigree is shown here. A. What is the inbreeding coefficient for individual IV-3? B. Based on the data shown in this pedigree, is individual IV-4 inbred?Based on this information (picture) A. What is the probability that a randomly sampled individual from the population has two copies of the a allele (that is, that it has an aa genotype)? B. What is the probability that both members of a randomly sampled married couple (man and woman) are aa at the asparagus-smelling gene? C. What is the probability that both members of a randomly sampled married couple (man and woman) are heterozygotes at this locus (meaning that each person has one allele A and one allele a)? D. Consider the type of couple described in (c). What is the probability that the first child of such a couple also has one A allele and one a allele (is a heterozygote)? Remember that the child must receive exactly one allele from each parent.Two different varieties of potato plants produce potatoes with thesame mean weight of 1.5 pounds. One variety has a very low variancefor potato wieght, and the other has a much higher variance. A. Discuss the possible reasons for the differences in variance.B. If you were a potato farmer, would you rather raise a varietywith a low or high variance? Explain your answer from apracticalpoint of view.C. If you were a potato breeder and you wanted to develop potatoeswith a heavier weight, would you choose the variety witha low or high variance? Explain your answer.
- A certain form of congenital glaucoma is caused by an autosomalrecessive allele. Assume that the mutation rate is 10-5 and that peoplewith this condition produce, on the average, only about 80% of theoffspring produced by people who do not have glaucoma.a. At equilibrium between mutation and selection, what will the frequencyof the gene for congenital glaucoma be?b. What will the frequency of the disease be in a randomly matingpopulation that is at equilibrium?2. Genes a and b are 21 m.u. apart when mapped inhighly inbred strain 1 of corn and 21 m.u. apart whenmapped in highly inbred strain 2. But when the distance is mapped by testcrossing the F1 progeny of across between strains 1 and 2, the two genes are only1.5 m.u. apart. What arrangement of genes a and band any potential rearrangement breakpoints couldexplain these results?While studying the genetics of the "Cute Faced Bat" face structure gene, three alleles ) are identified that produce 6 genotypes and 4 phenotypes “Cute”, “Super Cute Nose”, “Super Cute Face”, and “Super, Duper Cute” (equally expressing both Super Cute Face and Super Cute Nose). Given these observations, what can you conclude about the allele interactions?
- How might the Hardy Weinberg relationship be used to evaluate a new SNP genotyping technology using multiple individuals from a population? Group of answer choices a)If genotypes match the reference genome, the technology is sound. Otherwise, the technology may have problems accurately calling SNPs. b)If observed phenotypes follow Hardy Weinberg, the technology is sound. Otherwise, the technology may have problems accurately calling SNPs. c)If genotypes and allele frequencies follow Hardy Weinberg, the technology is sound. Otherwise, the technology may have problems accurately calling SNPs. d)None of the aboveCystic fibrosis (CF) is a recessive autosomal disorder. In certain populations of Northern European descent, the number of people born with this disorder is about 1 in 2500. Assuming Hardy- Weinberg equilibrium for this trait: A. What are the frequencies for the normal and CF alleles? B. What are the genotype frequencies of homozygous normal, heterozygous, and homozygous affected individuals? C. Assuming random mating, what is the probability that two phenotypically unaffected heterozygous carriers will choose each other as mates?A family pedigree is shown here. A. What is the inbreeding coefficient for individual IV-2? Who is/ are her parents’ common ancestor(s)? B. Based on the data shown in this pedigree, is individual III-4 inbred
