It appears that the Muller element F was an ancestral X chromosome in Diptera but that in the lineage leading to D. If only males display the disorder, it is most likely a Y-linked genetic disorder. In this pedigree, affected individuals have a disease causing the person to be born with feathers instead of hair, called Disease P.
Info Print Print. Human genetic disease. In X-linked recessive traits, the phenotype is expressed in males because they only have one X chromosome. So what's also very interesting is that you can imagine that for individuals who are XY or males, having these different mutations on the genes, on the X chromosome, is particularly problematic, because unlike females, there are not two X chromosomes that give you the potential of carrying a normal gene on the X chromosome.
A number of conditions like hemophilia, Duchenne muscular dystrophy, and Fragile X syndrome are sex-linked traits. Conversely, the farther apart two genes are located from each other along the chromosome, the more likely they are to be swapped with the alleles on the homologous chromosome.
Upon rare occasion, persons are identified with an imprinted gene disorder who show no family history and do not appear to carry any what chromosome is a sex linked trait located on in Raleigh in the expected gene.
If a sperm cell containing an X chromosome fertilizes an egg, the resulting zygote will be XX or female. Submit Feedback. A crossover event between the locations of two genes on a chromosome results in genetic recombinationor new combinations of alleles on a chromosome.

Dennis G, et al. These are traits that are found on either one of the chromosomes that determine sex, or the sex chromosomes. Selective sweep mapping under the QTL most proximal to the centromere revealed evidence for recent positive selection in the European population.
Expression of msl-2 causes assembly of dosage compensation regulators on the X chromosomes and female lethality in Drosophila.
