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).
The sex chromosomes are the X chromosome and the Y chromosome. In a man, both an X and a Y chromosome are present, giving an XY configuration. In a woman, there are two X chromosomes, giving an XX configuration. The X chromosome is therefore one of the two sex chromosomes that determines an individualâs gender.
