LETHAL GENES Meaning and
Definition
-
Lethal genes are genetic variations or mutations that, when present in an organism's DNA, lead to severe, often life-threatening conditions or diseases. These genes can cause the death of the individual who carries them, either before or shortly after birth, or they may be lethal at a later stage of development. Lethal genes typically have significant repercussions on the organism's physiological processes, resulting in severe impairments or malformations that are incompatible with normal life.
These genes are usually recessive, meaning that the individual must inherit two copies of the lethal gene (one from each parent) to manifest the lethal condition. When an organism carries only one copy of the lethal gene, it is considered a carrier and may not exhibit any visible signs of the condition. However, carriers can pass on the lethal gene to their offspring, potentially leading to lethal outcomes if both parents are carriers.
Lethal genes can be found across various organisms, including plants and animals. In agriculture and breeding, the identification of lethal genes is important to prevent breeding of individuals that could produce severely affected progeny. This helps maintain the overall health and viability of a population or breed, as breeding individuals with lethal genes can result in reduced fitness or increased mortality rates.
Understanding lethal genes is crucial in the context of genetic research and medicine as well. It allows scientists to identify and study the molecular mechanisms underlying certain lethal conditions, leading to potential advancements in diagnosis, treatment, and genetic counseling for affected individuals and their families.

Etymology of LETHAL GENES
The etymology of the term "lethal genes" can be broken down as follows:
1. Lethal: The term "lethal" finds its origins in the Late Latin word "lēthālis", which means "of or causing death". This was derived from the Latin word "lētum", meaning "death" or "destruction".
2. Genes: The term "genes" was coined by the Danish botanist and plant breeder Wilhelm Johannsen in 1909. It was derived from the Greek word "génos", which means "race", "kind", or "birth". Johannsen used this term to describe the fundamental units of heredity that determine specific traits in living organisms.
Therefore, the term "lethal genes" refers to genes that, when present in an organism's genetic makeup, cause death or severe harm to the individual.
