WebImagine that four genes on a single chromosome in a mutant phenotype of Drosophila cross over at half the normal rate as in the wild-type phenotype. How, if at all, would genetic maps of that chromosome differ between this mutant and the wild-type fly? ... Eye color in fruitflies is an X-linked character with red eyes (R) dominant to white eyes ... WebForensic DNA phenotyping (FDP) is an emerging technology that seeks to make probabilistic inferences regarding a person’s observable characteristics (“phenotype”) from DNA. The aim is to aid criminal investigations by helping to identify unknown suspected perpetrators, or to help with non-criminal missing persons cases.
