A silly trait performed with great energy on domestic animals to get them those characteristics that we prefer. It often leads to issues with inbreeding.
In a purebred organism, the pairs of alleles present are homozygous, meaning both alleles for a specific gene are identical. For example, if the gene in question is for flower color, a purebred organism may have two dominant alleles (AA) or two recessive alleles (aa). This uniformity in alleles ensures that the organism will consistently pass on the same traits to its offspring. Thus, purebred organisms exhibit stable and predictable phenotypic traits.

Purebred! :)
An organism that has two identical alleles for a trait is said to be homozygous for that trait. This means that both alleles are the same, either dominant or recessive. Homozygosity results in a consistent expression of the trait in the organism.
A purebred organism is the offspring of two homozygous parents, having either two dominant alleles, AA or two recessive alleles, aa. A hybrid is the offspring of two heterozygous parents, Aa.

Gg represents a hybrid genotype, where "G" is one allele and "g" is another allele for a particular gene. In a hybrid, the alleles are different, while a purebred would have two identical alleles (like GG or gg). Therefore, Gg indicates that the organism is heterozygous for that trait.
Purebred genotypes are those that are homozygous for a specific trait, meaning they have identical alleles for that trait. For instance, if the genotypes include AA or aa, these would be considered purebred, as both alleles are the same. In contrast, heterozygous genotypes, like Aa, are not purebred because they contain different alleles.
An organism that has two different alleles of the same gene is a heterozygous organism. Due to the various effects of different alleles, an organism's traits do not reveal its genetic composition.
