Cinnabar eyes (cn) and reduced bristles (rd) are autosomal recessive characters in Drosophila. A homozygous wild-type female was crossed to a reduced, cinnabar male, and the F1 males were then crossed to the F1 females to obtain the F2. Of the 400 F2 offspring obtained, 292 were wild type, 9 were cinnabar, 7 were reduced, and 92 were reduced and cinnabar.

In Drosophila, the allele dp determines long wings and dp determines short ("dumpy") wings. At a separate locus e* determines gray body and e determines ebony body. Both loci are autosomal. The original parents were purebred with antagonistic traits, one of the parents had long wings and ebony body. The dihybrid F1 was test crossed with the following result: Long, ebony 151 Long, gray 136 Short, gray 140 Short, ebony 145 Total You want to determine if the data support...

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 melanogaster, the recessive X-linked alleles white (w), miniature (m) and forked (f) give the phenotypes white eyes, miniature wings and forked brushes. The recombination between the w and m loci is 35%, and between the m and f loci, 20%. Wild-type males were crossed with females from a strain that was homozygous recessive for the three alleles, then the F1 flies were sibling mated. What phenotype frequencies are expected in F2 a) if there is no interference, and...

Please explain in details: White eyes is an X-linked recessive mutation and curly wings is an autosomal dominant mutation in Drosophila. What proportion of red eyed, curly winged females is expected in the F2 starting with a true breeding white eyed, non-curly female mating with a true breeding red eyed curly male. a. 1/16 b. 1/8 c. 3/8 d. 3/16 e. 1/32

multiple choice : 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 13 sn ct+ 36 sn+ ct 39 sn+ ct+ 12 1) What is the map distance between sn and...

In Drosophila, a cross between triply abnormal females with the X-linked recessive traits yellow bodies (y), echinus bristles (ec), and white eyes (w) and phenotypically normal males produces phenotypically normal F1 females. These F1 females are then testcrossed, and 1000 offspring occur as follows: Body Bristles Eyes number normal normal normal 447 yellow echinus white 442 yellow normal normal 18 normal echinus white 17 yellow normal white 28 normal echinus normal 33 normal normal white 8 yellow echinus normal 7...

Question 5 In Drosophila, ebony body (e) and rough eyes (r) are encoded by linked autosomal recessive genes on the third chromosome and are completely linked at O map units apart. A homozygous ebony female was crossed to a homozygous rough male. The F1 were all wild ty The F1 females were crossed to ebony, rough males. Give the phenotypes and their proportions in the F2. ebony, rough 20%, wildtype 20%, ebony 30%, rough 30% ebony, rough 30%, wildtype 30%,...
