2. You cross a homozygous wildtype female Drosophila (fruit fly) with a male that has a black body (bb). You mate two of the F1 (first generation) flies and examine the F2 (second generation) offspring. The phenotypes can be seen in the table below. a. Draw a pedigree to show the P, F1, and F2 generations. You only need to draw one fly with each phenotype for the F2 generation. seen in this cross. the expected values for a cross...

genetics: sorted independently and completely linked
Analyze the following fruit fly cross. In this cross there are two autosomal traits that are influenced by two distinct genes and the F2 generation came from crossing an F1 male with an F1 female. P: true breeding grey eyed; brown bodied males x true breeding red eyed; black bodied females F1: all offspring are red eyed; brown bodied F2: ? When the Fy flies are allowed to self cross, what percentage of F2...

c. Jwhite e For Cross #1, draw two Punnett squares in the space below to indicate what the F, and F, generation will be if the genes are autosomally linked. Specify the number of each phenotype you expect to be present in the F, generation, as well as the ratio of all phenotypes. Instructions: Answer the following questions and complete the data tables as you conduct your fruit fly crosses over the next two weeks. 1. Complete the following tables...

Using the Fly Breeder tool in the Fly Biolab, we analyze the heritability of eight other traits. Based on the phenotype ratios observed, explain whether each trait is caused by a dominant or recessive allele, and whether the trait is autosomal or sex-linked. Support each conclusion by referring to a completed Punnett Square. Trait 1: Purple Eyes Parent Phenotypes: Male- Red Eye Female- Purple Eye F1 Results (phenotype ratios): 100% red eyes F2 Results (phenotype ratios): 75% red: 25% purple...

Practice 7.1. Cross a female fly with the eyeless mutation (a) for eye shape but normal bristle (b+) to a male fly with wild type eye shape (a+) with shaven bristles (b). Both of these genes are located on Mate a female fly with mutant traits of a black body (c), bristle (b), and wing veins (v) to a wild- type male (normal body color (c+), bristle (b+), and wing size (v+)]. These three alleles are located on chromosome II...

Colorium is an autosomal dominant trait in Nutonian flies (identical to earth fruit flies in every way). There are two alleles at this locus: F = Dominant allele; flies with this allele cannot observe the color Fuschia; these flies have the Colorium phenotype. + = Wild type allele; flies who are homozygous for this allele can observe the color Fuschia; these flies do not have the Colorium phenotype. A cross of a true breeding male with Colorium and a true...

Assortment of genes on same chromosome In the fruit fly Drosophila, there is a dominant gene for normal wings and its recessive allele for vestigial wings. At another gene locus. there is a dominant gene for red eyes and its recessive allele for purple eyes. A female that was heterozygous at both gene loci was mated with a male that is homozygous for both recessive alleles. Knowing this, complete the sentences with the correct terms. 94% crossing over independent assortment...

2. Three genes and their mutations are found on the third chromosome in fruit fly Drosophila melanogaster. Of these three genes, scarlet eyes (st) are recessive to red eyes (st"), cbony body color (eb) is recessive to gray body color (eb"), and spineless (ss), the st presence of small bristles, is recessive to normal bristles (ss). You eb SS were given a heterozygous fly (st'st eb'eb ss'ss) and were asked to eb ss design an experiment to map the distance...
