uniparentaalinen

Uniparentaalinen refers to a genetic condition where an individual inherits genetic material from only one parent, typically due to the absence of the other parent's contribution. This can occur through various mechanisms, including:

1. Androgenesis: A male produces an egg (ovum) without fertilization, resulting in a genetic composition similar to that of the father.

2. Pseudopolyploidy: A zygote is formed with two sperm and no egg, leading to a genetic makeup similar to that of the father.

3. Aneuploidy: A zygote is formed with an abnormal number of chromosomes, often due to errors in meiosis.

Uniparentaalinen individuals are typically male and exhibit a range of physical and developmental abnormalities. They may have physical features resembling their father but not their mother, and their genetic makeup is unique, with no maternal contribution.

The term "uniparentaalinen" is often used in scientific and medical contexts to describe these rare genetic conditions. Research into uniparentaalinen individuals has contributed to our understanding of human genetics and development.
