GENETIC VARIANCE Meaning and
Definition
-
Genetic variance refers to the variation in genetic material or alleles within a population or a certain group of individuals. It is a concept widely used in genetics and evolutionary biology to measure the extent to which different individuals within a population possess different versions of genes or genetic traits.
Genetic variance arises due to the presence of multiple alleles or variants of a gene in a population. These alleles can exist in different frequencies, and the differences in their distribution contribute to the overall genetic variation observed in a population. Genetic variance can be quantified through statistical methods and calculations that measure the genetic differences between individuals for certain traits.
The presence of genetic variance is vital for the process of natural selection and evolution. It allows for the possibility of a diverse range of traits and characteristics within a population, which in turn increases the chances of some individuals being better adapted to their environment. This diversity is crucial for the survival and persistence of a population in a changing environment.
Understanding genetic variance is essential for various fields, including medicine, agriculture, and conservation biology. It helps researchers comprehend the occurrence and inheritance of genetic diseases, develop breeding programs for desired traits in plants and animals, and devise conservation strategies for preserving genetic diversity in endangered species.

Etymology of GENETIC VARIANCE
The word "genetic" originates from the Latin word "geneticus", which refers to "pertaining to generation" or "pertaining to origin". It is derived from the Latin word "genitus", meaning "begotten", and comes ultimately from the Proto-Indo-European root "*gene-", meaning "to give birth, beget".
The word "variance" comes from the Latin word "varius", meaning "diverse" or "different". It is derived from the Proto-Indo-European root "*wer-", meaning "to turn, bend". In English, "variance" refers to the state of being different, or deviating from a standard or expected value.
When combined, "genetic variance" is a term used in genetics and statistics to describe the variability or differences observed in the genetic makeup of individuals within a population.
