Backcrosses are a type of breeding technique that is used to introduce a desirable trait from one parent into the genetic makeup of another parent. This process is commonly used in agriculture, horticulture, and animal breeding to create new varieties of plants and animals that have desirable traits. In this article, we will explore the meaning and definitions of backcrosses, their origin, and their significance in different fields.
Definitions
Backcrosses, also known as backcross breeding, is a type of breeding technique that involves crossing a hybrid offspring with one of its parents. The resulting offspring will have genetic traits from both parents, but will also have a higher proportion of the genetic material from the parent that is used in the backcross.
Origin
The origin of backcrosses can be traced back to the early days of agriculture, when farmers began to selectively breed plants and animals to improve their productivity and quality. Over time, farmers discovered that by crossing a hybrid offspring with one of its parents, they could create new varieties that had desirable traits while still maintaining the genetic purity of the parent.
Meaning in different dictionaries
In the Merriam-Webster dictionary, backcrosses are defined as “a cross between a hybrid and one of its parents or an individual genetically identical to one of its parents”. In the Oxford English dictionary, backcrosses are defined as “a cross between a hybrid and one of its parents, especially to introduce a desired trait into the parent’s genetic makeup”.
Associations
Backcrosses are commonly associated with the breeding of plants, animals, and other organisms. They are used to create new varieties that have desirable traits such as disease resistance, improved yield, and better quality. Backcrosses are also associated with genetic research and the study of inheritance patterns.
Synonyms
Some synonyms of backcrosses include retrocross, repeated backcross, and recurrent backcross.
Antonyms
There are no specific antonyms for backcrosses, as it is a specific breeding technique.
