The phenotype of vestigial (short) wings (vg) in Drosophila melanogaster is caused by an autosomal recessive mutant allele that independently assorts with an autosomal recessive mutant allele for hairy (h) body. A parental cross was made between a fly that is homozygous for normal wings with a hairy body and a fly with vestigial wings that is homozygous for normal body hair. The wild-type F1 flies were crossed to each other and produced 1536 offspring. The phenotypes of the F2...

In Drosophila, b+ is the allele for normal body color and at the same gene b is the allele for black body color. A second gene controls wing shape. The shape can be either normal (vg+) or vestigial (vg). A cross is made between a homozygous wild type fly and fly with black body and vestigial wings. The offspring were then mated to black body, vestigial winged flies. The following segregation ratio was observed: Phenotype # Observed Wild Type (normal,...

A female fruit fly who is heterozygous with the phenotype gray body, red eyes & long wings is crossed with a male who is homozygous recessive (black body, purple eyes, vestigial wings). The observed offspring are shown below: # offspring, body color. eye color. wing length 411 gray red long 61 gray red vestigial 2 gray purple long 30 gray purple vestigial 28 black red long black red vestigial...

Pre-lecture lesson 2.12: Linkage and Gene Mapping You are charged with testing whether 2 different genes are independently assorting during meiosis in Drosophila melanogaster, the fruit fly The 2 genes you will be observing for this experiment are: Black: a recessive allele of this gene (b) results in a dark body color (somewhat similar to ebony, but a richer dark coloration that is less ashen-colored). The dominant allele for this gone (B) produces wild type body color Vestigial: a recessive...

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...

(b) Morgan actually obtained the following results: 965 offspring were gray body/long wings; 944 were black body/vestigial wings, 206 were gray/vestigial and 185 were black/long. With this information fill in the goodness of fit table (table 5) and cal- culate x (c) The critical value for this test is still 7.815. Does Morgan's study support or contradict the claim that body color and wing length obey Mendel's Principle of Independent Assortment? Defend your answer.

16. Use the following information to answer the questions below. Drosophila (fruit flies) usually have long wings (+) but mutations in two different genes can result in bent wings (bt) or vestigial wings (vg). If a homozygous bent wing fly is mated with a homozygous vestigial wing fly, which of the following offspring would you expect? a. 1/2 bent and vestigial to 1/2 normal b. 1/2 bent and 1/2 vestigial flies c. 3/4 bent to 1/4 vestigial ratio d. all...

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...
