Suppose that a geneticist discovers a new mutation in Drosophila melanogaster that causes the flies to shake and quiver.
She calls this mutation quiver, qu, and determines that it is due to an autosomal recessive gene. She wants to determine
whether the gene encoding quiver is linked to the recessive gene for vestigial wings, vg. She crosses a fly homozygous for
quiver and vestigial traits with a fly homozygous for the wild-type traits, and then uses the resulting F, females in a
testcross. She obtains the flies from this testcross.

Test the hypothesis that the genes quiver and vestigial assort independently by calculating the chi-squared, X², for this
hypothesis. Provide the X2 to one decimal place.

- Hardy-Weinberg Problems Please be sure to SHOW ALL WORK in order to get credit. This assignment will be graded for accuracy. *Hint: Remember what p and q represent. Determine first if I am asking for allele frequency or genotype/phenotype frequency. Then determine which equation is appropriate. What does p and q represent in the equations? Which equation do you use if I am asking for allele frequency? If the frequency of the recessive allele is 0.1, what is the frequency of the dominant allele? If the frequency of the dominant allele is 0.4, what is the frequency of the recessive allele? If the frequency of the dominant allele is 0.6, what is the frequency of the homozygous dominant genotype? If the frequency of the homozygous recessive genotype is 0.81, what is the frequency of the recessive allele? If the frequency of the homozygous dominant genotype is 0.25, what is the frequency of the dominant allele? If the frequency of the…arrow_forward3. Animation 12.1: This table shows results from allele-specific oligonucleotide hybridization analyses conducted on three different patients. The analyses all used the same probes constructed to test for the presence of a mutant gene. A plus sign (+) indicates hybridization occurred and a negative sign (-) indicates no hybridization occurred. Patient #1 Patient #2 Patient #3 Probe for normal allele Probe for mutant allele Which patient(s) is/are homozygous for the mutation and which patient(s) is/are heterozygous for the mutation? O Patients #2 and #3 are homozygous and Patient #1 is heterozygous for the mutation. O Patient #2 is homozygous and Patient #1 is heterozygous for the mutation. O Patient #1 is homozygous and Patients #2 and #3 are heterozygous for the mutation. O Patient # 1 is homozygous and Patient #2 is heterozygous for the mutation.arrow_forwardComplementation tests of distinct recessive mutants, 1 through 8, produce the data in the matrix below. A plus (+) indicates complementation, meaning the phenotype of the combined alleles is wild type, and a minus (-) indicates a failure to complement meaning that a mutant phenotype results. Assume that the missing mutant combinations would yield data consistent with the entries that are shown. How many complementation groups are formed by these eight mutants?

- Please help. Urgentarrow_forward1. DO NOT ROUND OFF YOUR ANSWERS PREMATURELY. Use the unrounded and complete values when computing for the genetic gain; 2. Upon encoding, all final answers should be rounded-off to TWO decimal places. Examples: 3.5798 = 3.58, 0.0079 = 0.01, 0.00000008 = 0.00; 2. Report your answers as NUMERIC VALUES only. Please exclude the units; 3. Write ONLY one answer for each question. Avoid using "or", "/", "&" and "and". Provide only what is asked to you; 4. AVOID using unnecessary PUNCTUATIONS (. , ? 1; ; etc.), SYMBOLS ( []{ } etc.) and SPACES (before or after your answer). Please follow these instructions carefully. Prediction of Genetic Gain. If the milk yield of a herd of cow is 6,479 kg while those kept for breeding is 6,890 kg, and the h2 estimate of milk yield is 0.85. And the generation interval of dairy cattle is 4 years. What will be the expected genetic gain in the milk yield (kg/year) of the next generation?arrow_forwardI need some help with this fill-in-the-blank problem. The answer choices are bolded and bracketed. Please see the attached photo to complete. 1. In the D2S441 locus, Sophie's allele [10, 12] is maternal and her allele 10 is paternal from [Sam or Bill only, Sam or Harry only, Bill or Harry only, Sam Bill or Harry (either 3)]. 2. Sophie's allele 13 for D19S433 is [maternal, paternal] and her allele 14 could have come from [Sam and Bill only, Sam and Harry only, Bill and Harry only, Sam Bill or Harry (either 3)]. 3. In the FGA locus, Sophie's allele [21, 22] is maternal and her other allele could have come only from [Sam, Bill, Harry]. 4. Based on all STRs in the 3 panels we studied, it is clear that [Sam, Bill, Harry] is Sophie's father. He has one allele of Sophie's alleles for all STR loci 5. Would these results stand in court as proof paternity: [Yes or No] 6. This type of DNA profiling can also be used to determine maternity.
