heredity

[həred′itē]

Etymology: L, hereditas, inheritance

1 the process by which particular traits or conditions are genetically transmitted from parents to offspring, causing resemblance of individuals related by descent. It involves the separation and recombination of genes during meiosis and fertilization and the further interaction of developmental influences and genetic material during embryogenesis.

2 the total genetic constitution of an individual; the sum of the qualities inherited from ancestors and the potentialities of transmitting these qualities to offspring.

heredity

the transmission of genetic traits from parents to offspring. The hereditary material is DNA in the ovum and sperm, so that the offspring's heredity is determined at the moment of conception.

Inside the nucleus of each germ cell are structures called chromosomes. A chromosome is composed of deoxyribonucleic acid (DNA) which is associated with histone proteins. Genes are segments of the DNA molecule; there are an estimated 100,000 genes in each cell. Most genes carry code for a specific protein which may be recognized as a specific hereditary trait. These traits are physical, biochemical and physiological. Thus genes affect not only the physical appearance of an animal but also its behavior, physiological makeup, its tendency to develop certain diseases, and the daily activities of all the cells of its body. See also inheritance.

Q. What pattern of heredity does diabetes follow? I know that baldness comes from your mother's father. How does diabetes travel through generations?

A. Ninety percent of children who develop type 1 diabetes actually have no relative with the disease. But it’s an auto immune disease. That means that some people are in risk of getting diabetes type 1. Depends on the immune system they inherited. It’s not “recessive” or “dominant”, if your parent has type 1 – you have a 25% chance of getting the risk factor.
