7:18 PM Three-point cross #3 2017-09-28 In Drosophila, the genes for withered wings (whd), smooth abdomen (sm) and speck body (sp) are located on chromosome 2 and are separated by the following map distances: whd-(30.5) A female with withered wings and a smooth abdomen was mated to a male with a speck body The resulting phenotypically wild-type females were mated with males that had the mutant phenotype for all three traits, producing 2000 offspring. Question: Assume that interference for these genes is 0.3. How many offspring are expected to have the following phenotypes? withered wings & speck body OR smooth abdomen Enter your answer as a whole number, round to the nearest integer Numerical Answer 15.5) sp ype your response 1 2 3 45 678 9 0 ABC space Go

    can you please help me with number 4? An example of linked genes in Drosophila The genes for wing shape and body color are linked (they are on the same chromosome) Drosophila and linked genes In the example shown left, wild type alleles are dominant and are given an upper case symbol of the mutant phenotype (Cu or Eb). This notation used for Drosophila departs from the convention of using the dominant gene to provide the symbol. This is necessary...

    In Drosophila (fruit flies) the genes how, dumpy and ebony are located on chromosome 3. LOF = loss of function. Flies homozygous for a LOF mutation (no gene product made) in ebony have dark black bodies. Flies homozygous for a LOF mutation (no gene product made) in dumpyhave truncated (short) wings. Flies homozygous for a partial LOF mutation (some gene product made but significantly less than normal) in how have wings that will not fold down (held out wings; that's...

    A cross in Drosophila involved the recessive, X-linked genes yellow (y), white (w), and cut (ch. A yellow-bodied, white-eyed female with normal wings was crossed to a male whose eyes and body were normal but whose wings were cut . The F, females were wild type for all three traits. • The F, males expressed the yellow-body and white-eye traits. The cross was carried to an F2 progeny, and only male offspring were tallied. On the basis of the data...

    Can you please help me with this problem: 3. The allele b gives Drosophila flies a black body, and b+ gives brown, the wild type phenotype. The allele wx of a separate gene gives waxy wings, and wx+ gives nonwaxy, the wild type phenotype. The allele cn of a third gene gives cinnabar eyes, and cn+ gives red, the wild-type phenotype. A female heterozygous for these three genes is testcrossed, and 1000 progeny are classified as follows: 5 wild type;...

    please help me!!! 5.) You have discovered mutants in two new gene mutants in Drosophila. One mutant, curl, has small, curly, nonfunctional wings. The other mutant, big, has enormous eyes. You decide to test if these two new genes are on chromosome #2, so you perform a three-gene linkage testcross using a gene that you know is on chromosome #2, trp, a mutant that cannot make its own tryptophan (and so must get it from its food). In all three...

    all of them please Question 10 (1 point) In Drosophila, the mutant black (b) has a black body and the wild-type (b+) has a gray body; the mutant vestigial (v) has wings that are short and crumpled compared the long wild-type wings (V+). These genes are linked and are located on the X- chromosome. A cross between a female fly and a black, vestigial winged male fly produced the following progeny: gray (b+), normal (v+) 20 gray (b+), vestigial (v)...
