Hi Gen214,
This video is about determining gene order and genetic map distances between the genes. This question in particular deals with no DCOs.
Enjoy!
Question below:
A gene called "forked" (f) produces shortened, bent, or split bristles and hairs in Drosophila. Another
gene called "outstretched" (od) results in wings being carried at right angles to the body. A third
gene called "garnet" (g) produces pinkish eye colour in young flies. Wild-type F1 females
heterozygous at all three loci were crossed to recessive males. The F2 data appear below:
Phenotypes Number
garnet, outstretched 57
garnet, forked 419
forked 60
outstretched 439
wild type | wilde tipe 15
garnet, outstretched, forked 10
Give the gene order and map units between these three loci.
