HETEROZYGOSITY LOSS Meaning and
Definition
-
Heterozygosity loss refers to a genetic phenomenon that occurs when an individual, population, or species experiences a reduction in the genetic diversity within their gene pool. It is specifically characterized by the loss of heterozygotes, which are individuals with two different alleles for a particular gene.
Heterozygosity is a measure of genetic variation within a population and is related to the presence of different alleles at a specific genetic locus. In a population with high heterozygosity, there is a greater diversity of alleles, which can provide advantages such as increased adaptability and resistance to diseases or environmental changes. Conversely, a decrease in heterozygosity, or heterozygosity loss, can have detrimental effects on the population's ability to adapt to changing conditions.
There are several factors that can lead to heterozygosity loss. One common cause is inbreeding, where individuals within a population mate with close relatives, resulting in a higher chance of inheriting identical alleles from both parents. Additionally, genetic drift, a random change in allele frequencies due to sampling error, can also contribute to heterozygosity loss, especially in small populations. Other factors such as natural disasters, population bottlenecks, or selective pressure can further exacerbate heterozygosity loss.
Overall, heterozygosity loss is a significant concern in conservation biology and population genetics, as it can reduce the overall genetic diversity and resilience of populations, increasing their vulnerability to genetic disorders, reduced fertility, and extinction risks.

Etymology of HETEROZYGOSITY LOSS
The term "Heterozygosity Loss" is a combination of three words: "Heterozygosity", "Loss", and a connecting word "of".
1. Heterozygosity: The word "heterozygosity" comes from the combination of two roots - "hetero" meaning "different" and "zygo" meaning "yoke" or "joining". In biology, heterozygosity refers to the presence of different alleles (alternate forms of genes) at a specific genetic locus in an organism's DNA. When an individual is heterozygous for a specific gene, it means they have inherited two different alleles for that gene, one from each parent.
2. Loss: The word "loss" comes from the Old English word "los", which means "destruction" or "ruin".
