Chapter 3, Problem 4P
In the fruit fly Drosophila melanogaster, very dark (ebony) body color is determined by the e allele. The e allele produces the normal wild-type, honey-colored body. In heterozygotes for the two alleles (but not in e+ e + homozygotes), a dark marking called the trident can be seen on the thorax, but otherwise the body is honey-colored. The e+ alleles is thus considered to be incompletely dominant to the e allele.
| a. | When female e+e+ flies are crossed to male e+e flies, what is the probability that progeny will have the dark trident marking? |
| b. | Animals with the trident marking mate among themselves. Of 300 progeny, how many would be expected to have a trident, how many ebony bodies, and how many honey-colored bodies? |

In Drosophila fruit flies, the genes for warped wings (dwp), rumpled bristles (rmp), and pallid wings (pld) are linked. A trihybrid female for all three allleles is crossed with homozygous recessive male for all three alleles and the offspring obtained showed the following phenotypes:
3 pld rmp dwp
428 pld rmp +
427 + + dwp
48 + rmp +
47 pld + dwp
23 pld + +
2 + + +
22 + rmp dwp
What is the order and map distance between these three alleles?
In Drosophila, ebony body colour is produced by a recessive gene a and wild-type (gray) body colour by its dominant allele a+. Vestigial wings are governed by a recessive gene vg, and normal wing size (wild type) by its dominant allele vg+. If wild-type dihybrid flies are crossed and produce 256 progeny, how many of these progeny flies are expected in each phenotypic class?
In Drosophila, singed bristles (sn) and cut wings (ct) are both caused by recessive, X-linked alleles. The wild type alleles (sn+ and ct+) are responsible for straight bristles and intact wings, respectively. A female homozygous for sn+ and ct+ is crossed to a sn ct male. The F1 flies are interbred. The F2 males are distributed as follows
sn ct
36
sn ct+
13
sn+ ct
12
sn+ ct+
39
What is the map distance between sn and ct?

- In Drosophila melanogaster, forked bristles are caused by an allele (Xf) that is X linked and recessive to an allele for normal bristles (X+). Brown eyes are caused by an allele (b) that is autosomal and recessive to an allele for red eyes (b +). A female fly that is homozygous for normal bristles and red eyes mates with a male fly that has forked bristles and brown eyes. The F1 are intercrossed to produce the F2. What will be the phenotypes and proportions of the F2 flies from this cross?arrow_forwardIn Drosophila, the allele for long legs (sl*) is wild-type and the allele for short legs (sl) is mutant. The allele for gray body color (b*) is wild-type and the allele for black body color (b') is mutant. The loci for leg length and body color are linked. Flies with sl*sl* b*b* genotypes are mated with flies that have sl s bb genotypes. A testcross was then performed in which the F, offspring with sl*sl b*b genotypes were mated with flies with sl sl. b'b genotypes. The phenotypes of 1000 offspring were recorded. There were 470 flies with long legs and grey body, 30 flies with long legs and black body, 30 flies with short legs and grey body, and 470 flies with short legs and black body.

A moth homozygous for red eyes and white-banded wings is crossed with a moth homozygous for the wild-type traits. The F1 have wild-type eyes and wild-type wings. The F1 are crossed with moths that have red eyes and white-banded wings in a testcross. The progeny of this testcross are wild-type eyes, wild-type wings red eyes, wild-type wings wild-type eyes, white-banded wings red eyes, white-banded wings a.
