The word "monohybrid" refers to a genetic cross between two individuals that differ in only one trait. The phonetic transcription of this word is /mɒnəʊhaɪbrɪd/. The first syllable, "mono," is pronounced with the short "o" sound, and the stress falls on the second syllable. The second part, "hybrid," is pronounced with a long "i" sound and stress on the first syllable. The spelling of this word may seem tricky, but once you understand the pronunciation, it becomes much easier to spell.
Monohybrid refers to a genetic cross or breeding experiment involving two individuals that differ in only one gene or character. In other words, it describes the study of inheritance patterns for a single trait or characteristic in offspring resulting from the mating of two parent organisms with contrasting phenotypes. The term is derived from the prefix "mono-", meaning one, and "hybrid", which represents the offspring produced from the mating of individuals from different genotypes or species.
Monohybrid crosses allow scientists to understand how traits are passed from one generation to the next. By selectively breeding two individuals with different variations of a particular gene, such as eye color in humans or seed color in plants, researchers can observe and analyze the inheritance pattern of that trait in their offspring. The phenotypes (observable characteristics) and genotypes (genetic compositions) of the offspring provide crucial insight into the mode of inheritance, whether it follows a dominant-recessive pattern, codominance, or incomplete dominance.
The study of monohybrid crosses was a fundamental concept developed by Gregor Mendel, often referred to as the father of modern genetics. His groundbreaking experiments with pea plants in the 19th century laid the foundation for understanding the principles of inheritance. Today, the monohybrid cross remains a valuable tool in genetics research, aiding in the understanding of patterns of inheritance and the prediction of trait expression in offspring.

The word "monohybrid" is derived from the combination of two roots: "mono" and "hybrid".
1. "Mono-" comes from the Greek word "monos", meaning "single" or "alone". In scientific terminology, "mono-" is used to indicate something that is single or solitary.
2. "Hybrid" comes from the Latin word "hybrida", which referred to the offspring of a tame sow and a wild boar. Over time, it came to represent the offspring of two different species or varieties.
Therefore, "monohybrid" combines "mono" (meaning single) and "hybrid" (meaning offspring of different varieties/species) to refer to a genetic cross or breeding experiment involving a single trait or characteristic between two individuals that differ in that trait.
