Finally, bow-legs is hypothesized to be X-linked
recessive in Drosophila melanogaster. The P1 virgin females were,
once again, homozygous wild type but the males were bow-legged.
There were 52 wild type males and 67 wild type females in the F1
generation. The F2 generation contained 30 wild type males, 75 wild
type females, 40 bow-legged males and no bow-legged females. Does
this data support or reject the hypothesis? Use chi square to prove
your position.
Homework Answers
here according to given hypothesis bow-legs in Drosophila melanogaster is X-linked. to prove this hypothesis we will makecross upto F2 progeny and find expected data to perform chi-square test
from chi- square test we find probability greater than 5 % ,and data supports the hypothesis chi-square test passed so we can accept the hypothesis

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...

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, the X-linked recessive mutation vermillion (v) causes bright red eyes, in contrast to the brick-red eyes caused by the wild-type allele. A separate autosomal recessive mutation, brown (bw), causes flies to have brown eyes. Flies carrying both mutations have no eye pigmentation and are white-eyed. Determine the F1 and F2 phenotypic ratios for each sex from the following crosses: (a) brown females X vermillion males (b) white-eyed females X wild-type males

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.

5. In Drosophila, males from a true-breeding stock with raspberry-colored eyes were mated to females from a true-breeding stock with sable-colored bodies. In the F1 generation, all the females had wild-type eye and body color, while all the males had wild-type eye color but sable-colored bodies. When F1 males and females were mated to each other, the F2 was composed of: 216 females with wild-type eyes and wild-type bodies 223 females with wild-type eyes and sable bodies 191 males with...

In Drosophila, the autosomal recessive brown eye color mutation
(b) displays interactions with both the X-linked recessive
vermilion mutation (v) and the autosomal recessive scarlet (s)
mutation. Flies homozygous for brown and simultaneously hemizygous
or homozygous for vermilion have white eyes. Flies simultaneously
homozygous for both the brown and scarlet mutations also have white
eyes. Flies that are wildtype at all 3 loci have wildtype eye
color. Flies that are homozygous or hemizygous for the recessive
