Answer #1

Number of recombinant gametes = recombination distance between the genes = distance between the genes

Number of parental gametes = 100 - number of recombinant gametes

Parental gametes (92%) -

sr+ e = 46%

sr e+ = 46%

Recombinant gametes (8%) -

sr+ e+ = 4%

sr e = 4%

Please rate high.

    In Drosophila, the genes sr (stripe thorax) and e(ebony body) are located 8 CM apart on chromosome 3. The wild type alleles, sr+ and et, are dominant over the mutant alleles. Consider a female fly that is heterozygous at both loc with the phase: sre / ste The proportion (%) of her gametes containing sr e alleles is expected to be The proportion (%) of her gametes containing sr+e+ alleles is expected to be The proportion (%) of her gametes...

    Explain how the positioning is used to calculate proportion. In Drosophila, genes a and b are located at positions 22.0 and 42.0 on chromosome 2, and genes c and d are located at positions 10.0 and 25.0 on chromosome 3 A fly homozygous for the wild-type alleles of these four genes was crossed with a fly homozygous for the reces- sive alleles, and the F, daughters were backcrossed to their quadruply recessive fathers. What offspring would you expect from this...

    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...

    37) The genes for mahogany eyes and ebony body are chromosome III in Drosophila. Assume that a mahogany-eyed female was mated to an ebony-bodied male and that the resulting F1 phenotypically wild-type females were mated to mahogany, ebony males. Of 1000 offspring, 325 were mahogany, 375 were ebony, 125 were wild type, and 125 were both mahogany and ebony. What is the distance between the mahogany and ebony genes? A) 50 CM B) 15 CM C) 25 CM D) 75...

    "Ebony body, held-out wings and sepia eyes are ALL RECESSIVE AND ALL ON CHROMOSOME 3. The COEFFICIENT of COINCIDENCE for chromosome 3 is 0.5. A homozygous ebony male is mated to a homozygous held out wing and sepia eyed female. The F1 are wild-type. An F1 female is test crossed to a fly that is homozygous for all three recessive alleles and they produce 1000 progeny. If ebony and held-out are separated by 12 map units, and held-out and sepia...
