b. Define gene symbols and genotypes of parents from the given data.

Cross Number of progeny
Straight wings-long bristles Straight wings-short bristles Curled wings-long bristles Curled wings-short bristles

Introduction:

Drosophila is used for the study of molecular and genetic functions since decades. in the given study, mutant type is crossed with wild type to obtain various combinations. Wild type characters of Drosophila are straight wings and long bristles, and mutant type characters are curled wings, and short bristles.

Unpacking the Problem 44John and Martha are contemplating having children, butJohn’s brother has galactosemia (an autosomal recessivedisease) and Martha’s great-grandmother also had galactosemia. Martha has a sister who has three children, none ofwhom have galactosemia. What is the probability that Johnand Martha’s first child will have galactosemia?1. Can the problem be restated as a pedigree? If so, writeone.2. Can parts of the problem be restated by using Punnettsquares?3. Can parts of the problem be restated by using branchdiagrams?4. In the pedigree, identify a mating that illustratesMendel’s first law.5. Define all the scientific terms in the problem, and lookup any other terms about which you are uncertain.6. What assumptions need to be made in answering thisproblem?7. Which unmentioned family members must be considered? Why?8. What statistical rules might be relevant, and in whatsituations can they be applied? Do such situations existin this problem?9. What are two generalities…
Hello, I need help answering number 40(INCLUDING SUB-PARTS) multiple choice questions. Pls and thank you! 40. A.) If all current mitochondrial DNA sequences in humans coalesce to one dated to 70,000 years ago, then: a) this mitochondrial Eve was the only female living 70,000 ago b) this mitochondrial DNA lineage is the only one persisting to the present time c) this mitochondrial Eve can be matched to a single male who lived 70,000 years ago (Y-chromosome Adam) d) mitochondrial DNA diversity 70,000 years ago was definitely higher than that present now B.) If the climate is warming faster than at any time in the last 800,000 years or more, then: a) strong directional selection for adaptations that allow survival and reproduction in a warmer world will be present b) sufficient additive genetic variance will be present to allow rapid adaptation to a warmer world c) mutation rates will increase to cause more adaptive mutations d) mutation rates will decrease due to the effect of heat on…
Unpacking Problem 731. Define homozygous, mutation, allele, closely linked, recessive, wild type, crossing over, nondisjunction, testcross, phenotype, and genotype.2. Does this problem concern sex linkage? Explain.3. How many chromosomes does Drosophila have?4. Draw a clear pedigree summarizing the results of crosses1, 2, and 3.5. Draw the gametes produced by both parents in cross 1.6. Draw the chromosome 4 constitution of the progeny ofcross 1.7. Is it surprising that the progeny of cross 1 are wild-typephenotype? What does this outcome tell you?8. Draw the chromosome 4 constitution of the male testerused in cross 2 and the gametes that he can produce.9. With respect to chromosome 4, what gametes can thefemale parent in cross 2 produce in the absence of nondisjunction? Which would be common and which rare?10. Draw first- and second-division meiotic nondisjunctionin the female parent of cross 2, as well as in the resultinggametes.11. Are any of the gametes from part 10 aneuploid?12.…
