TRUE BREEDING ORGANISM Meaning and
Definition
-
A "true breeding organism" is a term used in genetics to describe an individual organism that consistently produces offspring with the same traits as the parent organism when bred with other individuals of the same trait. These organisms are also known as "purebred" or "homozygous" organisms.
A true breeding organism has two identical alleles for a particular trait, one inherited from each parent. This means that during reproduction, the parent passes on the same allele for the trait to all its offspring, resulting in consistent expression of the trait in subsequent generations.
For example, if a true breeding plant with purple flowers is crossed with another true breeding plant with purple flowers, all their offspring will also have purple flowers. Similarly, if a true breeding organism with yellow seeds is bred with another true breeding organism with yellow seeds, all their offspring will have yellow seeds.
True breeding organisms are important in genetics because they provide a reliable source of individuals with the desired traits for further breeding experiments. They help establish a consistent genetic background for the study of inheritance patterns and the understanding of how traits are passed on from one generation to another.
In summary, a true breeding organism is one that consistently produces offspring with the same traits as the parent, resulting from the inheritance of identical alleles for a particular trait.
