You are doing lab work with a new species of beetle. You have isolated lines that breed true for either blue shells and long antenna, or green shells and short antenna. Crossing these lines yields F1 progeny with blue shells and long antenna. Crossing F1 progeny with beetles that have green shells and short antenna yield the following progeny:

                        blue shell, long antenna                      82

                        green shell, short antenna                   78

                        blue shell, short antenna                     37

                        green shell, long antenna                    43

                        total                                                  240

a. Which shell color and antenna length alleles are dominant?

b. Are the shell color locus and antenna length locus linked?

c. Check your answer to the previous question with the chi-square test.

d. If the genes are linked, calculate the recombination frequency between them.

    5. You started working in a Drospohila lab. You are studying two different autosomal traits, body color and antennae length. Gray body (B) is completely dominant to black body (b) and long antennae length (A) is completely dominant to short antennae length (a). You cross true-breeding gray bodied, long antennae files to true-breeding black bodied, short antennae. The F1 progeny all have gray bodies and long antennae. a. You perform a testcross to the F1 progeny produced from the parent...

    I included everything here , but i only need help with parts C-F You are working with a hypothetical fly and have found color and wing mutants. Preliminary work indicates that the mutant traits are recessive and the associated genes are not sex-linked, but beyond that you have no information. You first look at 2 genes, each with two alleles: "Borb" for body color and "Wor w" for wing surface. The red body phenotype is dominant to the yellow body...

    Show your work for all problems. 1) A diploid species of hamsters has a total of 4 chromosomes (2n = 4). A gene for whisker length is encoded by an autosomal gene and the long whisker allele (H) is dominant to the short whisker allele (h). A second gene located on the X chromosome is responsible for nose color. The brown nose allele (B) is dominant to the pink nose allele (b). A. (8 pts) A male with short whiskers...

    Drosophila genetics hw. Can someone help explain this You are doing a genetics experiment with the fruit fly. In the "P" generation, you cross two true-breeding flies. The female parent is brown and wingless and the male parent is black with normal wings. All of the flies in the F1 generation are brown and have normal wings. Indicate the alleles associated with dominant phenotypes by uppercase letters and alleles associated with recessive phenotypes by lowercase letters. Assume the genes are...

    Given: There is a two locus two allele system for a particular species of African antelope. One locus controls horn length and the two alleles are H and h. (HH) gives long horns, (Hh) gives short horns, and (hh) gives no horns. Only males can have horns. The second locus controls color pattern and has two alleles D and d. (DD) gives a dark color pattern to the face, (Dd) gives a dark color pattern to the face, and (dd)...

    1.Certain characteristics, like coat color in many animals, is influenced by multiple genes. The phenomenon during which the presence of a homozygous recessive genotype at one locus "overrides" or masks the phenotype that would otherwise be produced by the alleles at another locus (regardless of whether they are dominant or recessive) is called: pleiotropy codominance Punnett effect recessive Epistasis 2. Which of the following would be considered a pleiotropic gene? A gene that-along with several others-influences a single phenotype, such...
