Q

Describe the inheritance pattern of genes

A

Inheritance patterns differ for genes on sex chromosomes (chromosomes X and Y) compared to genes located on autosomes, non-sex chromosomes (chromosomes numbers 1-22). This is due to the fact that, in general, females carry two X chromosomes (XX), while males carry one X and one Y chromosome (XY). Therefore, females carry two copies of each X-linked gene, but males carry only one copy each of X-linked and Y-linked genes. Females carry no copies of Y-linked genes.

Q

Acute vs chronic inflammation

A

An acute inflammation is one that starts rapidly and becomes severe in a short space of time. Signs and symptoms are normally only present for a few days but may persist for a few weeks in some cases.

Chronic: slow onset, can last for years, and is caused by issue death and the thickening and scarring of connective tissue
