Monohybrid - English Definition & Meaning

Definition

A monohybrid cross is a genetic cross between parents who differ in only one trait. This cross helps to determine the inheritance pattern of that single trait. It focuses on the alleles (different forms of a gene) for one specific gene. The parents are usually homozygous for different alleles, meaning one parent has two identical dominant alleles and the other has two identical recessive alleles. Monohybrid crosses are simple and effective tools to demonstrate Mendel's laws of segregation. Think of it like flipping a coin to see which side lands up!

Etymology

The term 'monohybrid' comes from the Greek words 'mono,' meaning 'single,' and 'hybrid,' referring to a cross between two different organisms. The term was popularized by Gregor Mendel in the 19th century. His experiments using monohybrid crosses with pea plants laid the foundation for modern genetics. Mendel's work helped establish the concept of genes and alleles.
