Answer-

Given that the a rudimentary wing called "vestigial (w)" and dark body color called "ebony (e)" are inherited at independent loci and are recessive to their dominant wild-type counterparts, full wing (W) and gray body color (E).

Cross between Dihybrid wild-type males and females is, WwEe* WwEe = WWEE (1/16), WWEe (2/16), WwEE (2/16), WwEe (4/16), WWee (1/16), Wwee (2/16), wwEE (1/16), wwEe (2/16), wwee (1/16).

Means, the occurance of phenotypic ratio is, 9: 3: 3: 1

Part A. How many progeny flies are expected to have vestigial wings and gray bodies -----------> 900 (3/16* 4800)

Part B. How many progeny flies are expected to have full wings and gray bodies ----------> 2700 (9/16* 4800)

Part C. How many progeny flies are expected to have vestigial wings and ebony bodies ---------> 300 (1/16* 4800)

Part D. How many progeny flies are expected to have full wings and ebony bodies ---------> 900 (3/16* 4800).

    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...

    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,...

    Scalloped (sd) wing is an X-linked recessive and ebony (e) body color is an autosomal recessive mutation in Drosophila.

    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...

    E10 from Brooker: In fruit flies, curved wings are recessive to straight wings, and ebony body is recessive to gray body. A cross was made berween true-breeding flies with curved wings and pray bodies and flies with straight wings and ebony bodies. The F1 offspring were then mated to flies with curved wings and ebony bodies to produce an F2 generation. A. Diagram the genotypes of this cross starting with the parental generation and ending with the Frencration B. What...
