- Please explain how I can solve this. Thank you You wanted to draw a linkage map for three genes in the fruit fly (A, B, C) that you suspect are linked. You have done a three-point testcross and found that out of the 1500 progeny in the cross, 612 are a · b · c, 603 are A · B · C, 93 are a · B · C, 85 are A · b · c, 53 are a · b · C, 47 are A · B · c, 5 are A · b · C, and 2 are a · B · c. From this data, you can deduce that the genes are linked and the distance between B and C is:Complete the problem below and upload your work here. Partial credit will be considered. In corn, purple kernels (P) are dominant over yellow kernels (p) and round kernels (R) are dominant to wrinkled kernels (r). In a cross of PpRr (purple, round) with a pprr (yellow, wrinkled) plant, the following progeny were observed: Phenotype Observed Expected (O-E) (O-E)2/E Purple, Round 117 Yellow, Round 126 Purple, Wrinkled 130 Yellow, Wrinkled 127 Total=500 Fill out the expected values in the chart above and calculate the Chi-Square value for your table, look up the p value associated with the Chi-Square. How many degrees of freedom do you have in this cross? 2. What is your Chi Square value? 3. What is the p value for this cross and what does your value mean? Make sure to explain the p value clearly in a couple of sentences.Question- QUESTION 1 Consider three linked genes: A, B, C. Percent recombination between gene B and C is 11% and no crossing over occurs between A and B. If a heterozygote in cis conformation is test crossed, what is the probability of an offspring with the genotype AaBbcc? A. 0.011 B. 0.055 C.0.022 D.0.089 E. 0.045
- Question:- A farmer decides to cross two tomato plants. One of the plants is a dihybrid for genes G and H. The other is homozygous recessive for gene G but homozygous dominant for gene H. Which of the following offspring genotypes would be recombinants? Select all that apply. Select one or more: a. GgHH b. All of the above are recombinant c. ggHH d. None of the above are recombinant e. ggHh f. GgHhPEDIGREE ANALYSIS ANSWER THE FOLLOWING QUESTIONS 1. The pedigree below shows a family's pedigree for colorblindness. Which sex can be carriers of colorblindness and not have it? 2. With this in mind, what kind of trait is colorblindness? 3. Why dies individual IV-7 have colorblindness? 4. Why do all the daughters in generation II carry the colorblind gene? 5. Name two (2) IV generation colorblind males.Sample problems related to non Mendelian inheritanceRead, analyze and answer completely the following problems: 1. Explain why it is possible for the proband in the following pedigree to have children of blood types A, B, and AB. Considering epistatic genes, what are the possible genotypes of II-2? 2. Agouti (A) is wild type and produces alternating bands of pigment on each hair. Black (a) is recessive to agouti. A mutation on gene B (recessive b) can eliminate all color. In a cross between agouti (AABB) and albino (aabb) mice, what genotypes, phenotypes, and proportions are expected in the offspring in F1 and F2 generations?
- PLEASE WRITE ALL STEPS OUT. STEP BY STEP The recombination frequency between the A and B loci above is 32%. An offspring of the cross AABB x aabb is crossed in a test cross. How many progeny with the genotype Aabb would you expect out of 100 progeny from this test cross? O 16 O 32 68 34I don't really understand how to solve this question. For part a, I think my approach would be to find the genotypes of the parents first, and find the genotype of the F1. For part B, I would like to get some clarifications on the difference between linked genes with no crossing over vs. unlinked genes when approaching Punnett square type questions. Thank you also answer part a and bDrosohpila Punnet Square of Crosses. I need results of F1 & F2 generation using Punnett Squares for: Make Punnet Squares of the following crosses •Drosophila Female wildtype cross Male White-eye •Drosophila Male wildtype cross Female White-eye •Drosophila Female Wild Type cross Male Scarlet Eye •Drosophila Male Wild Type cross Female Scarlet Eye Also, Which allele is heterozygous and which is homozygous, & which is dominant and which is recessive?

Allele phenotypes: R = red, r = white, T = thin leaf, t = broad leaf Cross: RR; Tt x Rr; tt Red with thin leaves ___________ Red with broad leaves ___________ White with thin leaves ___________ White with broad leaves __________ PLEASE show work and give an explanation... Thank you!What is/are the phenotypes of the recombinant offspring of the F2generation?a. red eyes, long wingsb. white eyes, miniature wingsc. red eyes, long wings and white eyes, miniature wingsd. red eyes, miniature wings and white eyes, long wings [Answer the multiple-choice questions based on the following experiment:P generation: True-breeding flies with red eyes and long wings werecrossed to flies with white eyes and miniature wings. All F1 offspringhad red eyes and long wings.The F1 female flies were then crossed to males with white eyes and miniaturewings. The following results were obtained for the F2 generation:129 red eyes, long wings133 white eyes, miniature wings71 red eyes, miniature wings67 white eyes, long wings]Direction: Solve the following problems using Mendelian principles of heredity. Show your complete solution. 1. Mr. Allan Cruz has a genotype of DdEeFf, where the D and E loci are on the large chromosome and the F locus is on the small chromosome. This cell was taken from an F1 organism that resulted from the cross of two true breeding parents of the following genotypes. Parent 1: DDeeFF and Parent 2: ddEEff Among the children of Mr.Cruz’s parents, what is the chance of having the same genotype as Allan?
