A doctor may also suggest blood tests, a wound culture, or other tests to help rule out a blood clot deep in the veins of the legs. Cellulitis in the lower leg is characterized by signs and symptoms similar to those of a deep vein thrombosis, such as warmth, pain, and swelling (inflammation).
Sex linkage applies to genes that are located on the sex chromosomes. These genes are considered sex-linked because their expression and inheritance patterns differ between males and females. While sex linkage is not the same as genetic linkage, sex-linked genes can be genetically linked (see bottom of page).
If a gene is located on the Y chromosome, it is a Y-linked gene. These genes are only inherited by males because, in most instances, males have a genotype of (XY). Females do not have the Y sex chromosome. Genes that are found on the X chromosome are called X-linked genes.
