Yes, it is possible to undo a genetically modified trait in an organism through genetic engineering techniques like gene editing or selective breeding. By introducing targeted genetic changes or breeding with non-modified individuals, it is possible to reverse or eliminate the modified trait in subsequent generations.
An organism with two like alleles for a trait is homozygous for that trait.
Bt cotton is an example of genetically modified organism.
Genetically modified foods happened because man discovered that a gene could be removed from one species and forced into the cells of another species to bring about a desired trait in the host, or that a gene could be removed from an organism, modified in some way, and inserted back into the same organism. In the most common genetically modified foods today (2015), the desired trait is either resistance to a herbicide or to produce an insecticide in the plant itself, although there are some other, less common traits produced through genetic modification.
an organism that has two different alleles for a trait is heterozygous
An organism that has two different alleles for a given trait is referred to as heterozygous for that trait. For example, if one allele codes for a dominant trait and the other for a recessive trait, the dominant trait will typically be expressed in the organism's phenotype. This genetic variation can contribute to diversity within a population and may influence the organism's adaptability to its environment.
Acquired Trait
This could be called a trait (inheritance).
It is called the phenotype or phenotypic trait.
A recessive trait only appears in an organism when it is homozygous for that trait, meaning it has two copies of the recessive allele. This occurs when an organism inherits the recessive allele from both parents.
