- You design Drosophila crosses to provide recombinationdata for gene a, which is located on the chromosome shownin Figure 15.12. Gene a has recombination frequencies of14% with the vestigial wing locus and 26% with the browneye locus. Approximately where is a located along thechromosome?arrow_forward1. What is the processes of mitosis and meiosis indicating where the similarities lie and in which aspects they differ. What is the primary reason for each type of cell division by indicating the roles that mitosis and meiosis play in human reproduction and development? 2. Explain what is meant by the term ‘linked genes’ with respect to homologous recombination. For example, if an organism is heterozygous at two genetic loci on the same chromosome, in what way does the position of these alleles with respect to each other affect how they are transmitted to gametes during meiosis?arrow_forwardBiologyarrow_forward
- Item 10 10 of 15 > A cross in Drosophila melanogaster involved the recessive X-linked genes for white eye (w), yellow body (y), and cut wings (c). A wild-type tri-hybrid female was crossed with wild-type males and only the male offspring were tallied. On the basis of the results shown below, which of the choices shown best represents the genetic map of the three loci on the X-chromosome?

Let’s assume ananimal of this species is AaLl; A is linked to l, and a is linked to L.Draw the chromosomes labeled with these alleles, and explainhow mitotic recombination could produce a twin spot with onespot having albino pigmentation and long fur and the other havingdark pigmentation and short fur.arrow_forwardYou have a 5'(A/T)-3' SNV potential. Draw out to explain why using the sense strand and template strand would both yield the same color if you were heterozygous at this SNV location. (The color is red, by the way.) • How do you distinguish between sex-linked and limited expression in male traits in pedigrees? • You are checking a reciprocal cross and you get a chi square value of 7? = 4.08, p = 0.0434. Is this a significant difference? If so, propose an explanation. If not, explain how you know.arrow_forward
- In a series of mapping experiments, the recombination frequencies for four different linked genes of the Drosophila fly were determined, as shown in the figure. Based on this information, what is the most probable order of these genes on the chromosome? b 0 cn 90 rb 3.5 6.5 0 vg 19 9.0 16 0 b cn rb vg The numbers in the boxes are the recombination frequencies in between the genes (in percent).

In the plant Arabidopsis thaliana, a geneticist is interested in the development of trichomes (small projections). A large screen turns up two mutant plants (A and B) that have no trichomes, and these mutants seem to be potentially useful in studying trichome development. (If they were determined by single-gene mutations, then finding the normal and abnormal functions of these genes would be instructive.) Each plant is crossed with wild type; in both cases, the next generation (F1) had normal trichomes. When F1 plants were selfed, the resulting F2’s were as follows: F2 from mutant A: 602 normal; 198 no trichomes F2 from mutant B: 267 normal; 93 no trichomesa. What do these results show? Include proposed genotypes of all plants in your answer. b. Under your explanation to part a, is it possible to confidently predict the F1 from crossing the original mutant A with the original mutant B?arrow_forwardIn a 4th year honours project, Amy described short nucleotide polymorphism (SNP) on chromosome #1 of drosophila. Among this polymorphism for the DM3 locus, Amy described 2 alleles (DM1" and DM1°): 5'.TCTTGATC. 3' DM1T 3'.AGAACTAG. 5' or 5'.TCTCGATC.3' 3'.AGAGCTAG. 5' DM1C Amy then wanted to test if the DM1 SNP was linked to the gene for purple eyes. To do so, she first generated heterozygous flies by crossing true breeding red eyed flies with the DM1" marker with true- breeding purple eyed drosophila with the DM1C marker: pr+ PM1 heterozygote! pr DMIT She then did a testcross to perform a linkage analysis between the DM3 marker and the gene for purple eyes: pr+ DM1C pr PMIT pr DMIC pr DMIC X A) Complete the following table by indicating the types of gametes the heterozygous fly can produce (column 1); whether or not the gamete is of the parental type (P) or a recombinant (R) (column 2); and the genotype of the F2 progeny (column 3).

- In Drosophila (fruit flies), pink eyes (P), curled wings (C), a hairy body (H), and an ebony body (E) are determined by genes located on the same chromosome. Gene Combination Recombination Frequency E/H 41.7% C/H 18.2% E/P 22% H/P 19.7% Which of the following gene maps shows the gene sequence on this chromosome?arrow_forwardHas the DNA sequence of the eye color gene been changed in part (b) compared with part (a)? How do we explain the phenotypic difference?arrow_forward. Genomes A, B, and C all have basic chromosomenumbers (x) of nine. These genomes were derivedoriginally from plant species that had diverged from each other sufficiently far back in the evolutionarypast that the chromosomes from one genome can nolonger pair with the chromosomes from any other genome. For plants with the following kinds of euploidchromosome complements, (i) state the number ofchromosomes in the organism; (ii) provide terms thatdescribe the individual’s genetic makeup as accurately as possible; (iii) state whether or not it is likelythat this plant will be fertile, and if so, give the number of chromosomes (n) in the gametes.a.
