RECESSIVE GENES Meaning and
Definition
-
Recessive genes refer to a specific type of gene that manifests its characteristics or traits only in the absence of a dominant version of the same gene. In genetics, genes are segments of DNA that encode instructions for the creation of specific proteins that determine various traits or characteristics of an organism. Each individual inherits two copies of each gene, one from each parent.
Recessive genes are characterized by their ability to be masked or overridden by the presence of a dominant gene. Dominant genes are those that express their traits even when an individual carries only one copy of the gene. On the other hand, recessive genes require the absence of a dominant gene to express their traits.
When both copies of a gene are recessive, the individual is said to be homozygous for that gene, and the trait associated with that recessive gene is observed. Conversely, if at least one copy of the gene is dominant, the dominant trait is displayed, and the recessive trait remains hidden or unexpressed.
Recessive genes often play a significant role in genetic inheritance patterns, particularly in the context of genetic disorders. Many genetic diseases are caused by the presence of a recessive gene that leads to the expression of a harmful trait when both copies of the gene are inherited. Understanding the nature of recessive genes is crucial for studying and predicting genetic inheritance patterns.

Etymology of RECESSIVE GENES
The term "recessive genes" comes from the field of genetics and is derived from the Latin word "recessus", which means "withdrawn" or "hidden". In genetics, recessive genes are those that are masked or overshadowed by dominant genes, resulting in their traits not being expressed in the presence of dominant alleles. The concept of recessive genes was first proposed by Gregor Mendel, the father of modern genetics, in the mid-19th century.
