Men have this dosage because, well, they only have one X chromosome! Women have the same dosage for a different reason: they shut down one of their two X chromosomes in a process called X-inactivation. towable rvs with washer and dryer near me

WebFemales have two X-chromosomes. Males have one X and one Y-chromosome. With both an X and a Y-chromosome, males inherit both X and Y-linked traits, while females only inherit X-linked traits. Since males have only one copy of each sex chromosome, they are hemizygous for all sex-linked genes, and they always express the phenotype * of the allele ... WebSex-linked traits are characteristics that are determined by genes located on the sex chromosomes. Inheritance patterns for these traits can differ for males and females, since the X and Y chromosomes differ. One example of a sex-linked trait is color blindness, which is primarily seen in males. X-inactivation can also influence the expression ...

The red body phenotype is dominant to the yellow body phenotype and smooth wings are dominant to crinkled wings.
