You continue your experiments with the black mutation on chromosome II. You cross the reciprocal translocation strain to the black pure line to generate F, flies that are both translocation heterozygotes and Bb heterozygotes. As before, you testcross F, males and females in two separate experiments. F, males x pure black females (Note: There is no crossing over in the F, males.) F1 females x pure black males (Note: Crossing over may occur in the F, females.) Cross 424 black, fully fertile 426 wild-type, semi-sterile 73 black, semi-sterile 77 wild-type, fully fertile 1/2 black, fully fertile 1/2 wild-type, semi-sterile F2 Progeny What can you conclude from these results? Select the three correct statements. The F2 progeny in both experiments contain recombinants. The F2 progeny contain recombinants only when F, females are testcrossed. None of the F2 progeny classes require crossing over. Some of the F2 progeny classes require crossing over; others do not. Chromosome Il is one of the chromosomes involved in the reciprocal balanced translocation.

A 5-year-old boy with mental retardation is grossly obese and has facial features of Prader-Willi syndrome (PWS). Karyotyping and fluorescent in situ hybridization studies do not show deletion in the usual site on chromosome 15. Which of the following findings is most likely to confirm PWS in this child? ✓ A Deletion in the short arm of chromosome 15 BY Duplication within chromosome 15 Large trinucleotide repeat expansion in the PWS area of chromosome 15 D) Maternal origin of both chromosomes 15 -Translocation in the short arm of chromosome 15
A tomato geneticist attempts to assign five recessivemutations to specific chromosomes by using trisomics.She crosses each homozygous mutant (2n) with each ofthree trisomics, in which chromosomes 1, 7, and 10 takepart. From these crosses, the geneticist selects trisomicprogeny (which are less vigorous) and backcrosses themto the appropriate homozygous recessive. The diploidprogeny from these crosses are examined. Her results, inwhich the ratios are wild type:mutant, are as follows:Which of the mutations can the geneticist assign towhich chromosomes? (Explain your answer fully.)

A scientist working with Drosophila flies studies wing length, an X-linked characteristic. He has pure-breeding lines of short-winged and long-winged flies available. He decides to use reciprocal crosses for his work.i) What are reciprocal crosses? ii) Provide an example of the reciprocal crosses this scientist will do.iii) If the gene for wing length was sex-linked, but present in the pseudoautosomal region, what would you expect the outcome of a reciprocal cross to be with regards to males and females?

The recombination frequency in a cross can never exceed 50%. Explain why is this limit?
Part A You start your experiments with the eyeless mutation on chromosome IV. You cross the reciprocal translocation strain to the eyeless pure line to generate F, flies that are both translocation heterozygotes and Ee heterozygotes. You decide to testcross F, males and females in two separate experiments to take advantage of the fact that crossing over does not occur in male Drosophila. F, males x pure eyeless females (Note: There is no crossing over F, females x pure eyeless males (Note: Crossing over in the F, males.) Cross may occur in the F, females.) 4 eyeless, fully fertile 4 wild-type, semi-sterile 4 eyeless, semi-sterile 4 wild-type, fully fertile 4 eyeless, fully fertile 4 wild-type, semi-sterile 4 eyeless, semi-sterile 4 wild-type, fully fertile F, Progeny What can you conclude from these results?

In a mutant screen in Drosophila, you identified a gene related to memory, as evidenced by the inability of recessive homozygotes to learn to associate a particular scent with the availability of food. Given another line of flies with an autosomal mutation that produces orange eyes, design a series of crosses to determine the map distance between these two loci. You do not need to calculate recombination frequency.
A D. melanogaster male is homozygous for a translocation between chromosomes 2 and 3. This fly is otherwise wild-type. This male is crossed to a female fly that is homozygous for normal chromosome order and is homozygous for dumpy wings (dy), a recessive on chromosome 2 and sepia eyes (se), a recessive on chromosome 3. A male progeny from the above cross is test-crossed to a female fly that is homozygous for dy and se. What progeny phenotypes and frequencies are expected from this second cross? Answer choices 1/2 wild-type and 1/2 dumpy and sepia 1/4 wild-type, 1/4 dumpy, 1/4 sepia, 1/4 dumpy and sepia All dumpy and sepia 2/3 wild-type, 1/3 dumpy and sepia 9/16 wild-type, 3/16 dumpy, 3/16 sepia, 1/16 dumpy and sepia
Are two genes linked if not linked to the same marker on a chromosome.? Let's say we want to figure out whether two genes are linked on a particular chromosome so we cross-test them to a marker gene on that chromosome. Gene A is found to have an approximate 50% recombinant frequency so we say it's not linked to the marker. The other gene B however is found to have 40% recombinant frequency with our marker so we say it's linked. Now the question is are the two Genes A and B linked or not? Please explain your reasoning.
