The incomplete dominant phenotype is light tan. If a heterozygous female is crossed with heterozygous male, what will be the phenotypic ratio of the progeny? A) 1 dark brown: 2 light brown: 1 white. B) 3 dark brown: 1 white C). all dark brown D) all light tan E) cannot be determined CS Scanned with CamScannerQUESTION 7 A trihybrid individual with the genotype AaDdEe is testcrossed with an aaddee individual. The resulting offspring are as follows: ADe 880 aDE 67 AdE 45 ade 4 ADE 3 aDe 57 Ade 57 adE 887 Total = 2000 a) Determine the allele arrangement and gene order in the trihybrid parent. Give your answer using the PQr/pqR notation. b) Draw a chromosome map for these genes. Give your map distances to two decimal places. (Use underline or underscore (_) to draw the line for the map)QUESTION 6 Assume that a researcher is studying coat color in voles. Three strains of white vole have been isolated: milky, blanc, and weiss. White is a recessive trait in each strain. Homozygous white voles are obtained for each strain. Consider the following crosses: milky X weiss = all white progeny (mutant) milky X blanc = all brown (wild-type vole color) blanc X weiss = all brown (wild-type vole color) The conclusion most consistent with these results is O A all three strains have mutations in the same gene. O B. all three strains have mutations in different genes. OC. milky and blanc have mutations on the same gene, weiss has a mutation in a different gene. D. milky and weiss have mutations on the same gene, blanc has a mutation in a different gene. O E. weiss and blanc have mutations on the same gene, milky has a mutation in a different gene.
- Question 5 [HINT: This problem wants you to calculate gene number from the proportion of individuals in the extreme classes, not from the number of phenotypes.] A farmer has two pure-breeding varieties of tomatoes: Little Pete (average fruit diameter 2cm) and Big Boy (average fruit diameter 14 cm). The farmer crosses Little Pete and Big Boy and obtains F1 plants with fruit averaging 8cm in diameter. When he intercrosses the F1s to obtain F2s, he examines 2000 F2 plants and finds two plants that produce fruit even smaller than Little Pete and three plants that produce fruit even larger than Big Boy. From these data, how many genes can we infer are involved in controlling fruit size in these plants? What is the genotype of Little Pete? What is the genotype of Big Boy? What is the genotype of the F1s? What are the genotypes that are bigger than Big Boy? What are the genotypes that are smaller than Little Pete?QUESTION 6 Genes a, b, and c are linked, and pairwise crosses gave the following distances: a-b 20 cM b-c 2 cM a-c 22 cM Which gene is in the middle? O a O It's not possible to tell without additional information. QUESTION 7 A man and woman both have tpe AB blood and are carriers for the Bombay mutation. What is the probability their first child will be phenotypically O (Bombay)? O 1/4 O 1/16 O 1/2 O 3/16 QUESTION 8 The Bombay phenotype occurs because: O Rh antibodies can travel across the placenta and cause an incompatibility reaction. O an individual is homozygous recessive at the Rh locus. O the H substance is not present and so no A or Bantigens can be produced. O an individual does not haveor alleles, and so cannot produce the corresponding antigens.Question: Red color (R) allele is dominant over blue color (r) for carnations (a type of flower). You will cross a heterozygous red carnation with a blue carnation. Show all your work filling out the required parts of the diagram. Then, select the correct statement below.

- Question #2: Recombination is a process that creates genetic diversity during meiosis. Below is the average amount of recombination (y-axis) in several species of eukaryotes (shown on the x). SAR=Stramenopiles-Alveolates-Rhizaria Eukaryote log recombination rate (cM/MI SAR fungi other animals unseg, worms insects www molluses fishes crustaceans amphibians + reptile DO aves mammals other plants gnoliids magnolii basal eudicots superrosids superasterids lilioids+alismatids commelinids conifers a) What do you notice about the amounts of recombination in the various species? b) This paper found that recombination is positively correlated with gene density (number of genes per kb of chromosome) and negatively correlated with the density of repetitive elements (areas of the genome that are repetitive and do not encode genes). Why might this be the case? c) A cross was made between two individuals (AaBbxAaBb) where A codes for red eyes, a codes for blue eyes, B codes for curly wings, and b…Question:- 3. Wild type Drosophila has red eyes and gray body*. Autosomal recessive mutations sepia (se) and ebony (e) modify the eye and body color, respectively. What kind of a cross (or crosses) can you set up to determine whether the two genes are linked? You have several lines to choose from: a pure-breeding wild type line (where alleles for both, sepia and ebony are wild type), a double homozygous recessive line, a pure breeding sepia mutant line and a pure breeding ebony mutant line. You don’t have to use all of them. (a) Write down the cross (or crosses, if necessary) which will allow you to determine linkage; include genotypes of both crossed individuals (b) What kind of results (offspring) do you expect if the two genes are linked? (c) What kind of results (offspring) do you expect if the two genes are not linked? For (b) and (c), state the phenotypes, genotypes and numbers.Question #1 a. Explain why there is a non-Mendelian 2:1 yellow/agouti phenotypic ratio in this cross. b. What is the Raly gene? What does it encode? How does it relate to the lethality of Ay? c. A heterozygous mouse AAy does not produce enough pigment and it is yellow. Homozygous individuals die during development, but AAy heterozygous do not. Why? You may use any graphic aid to explain this, if necessary. This means that you may use a Punnett square or a forking segregation diagram, or computations with fractions.
