Some novel rules of the biological heterozygous effects

Abstract

The pure of an individual is relative to the hybrid. No two identical organisms are found on the earth at the level of nucleotide sequence. After two parents mating, the variations of their offspring will occur in the nucleotide sequence compared to their parents, which are called biological heterozygous effect. However, the molecular bases for this phenomenon remain elusive. In our view, biological heterozygous effects at least follow the below rules: Firstly, the contribution of the outcome of traits passed from parents to offspring is not equal. Secondly, progeny variation across the heterozygous individuals is lineage-specific dependent and some difference is found among the individuals within a family. Thirdly, biological variation is absolute, random, non-directional, and is fixed and forms a new species while other variation is getting into the blind branch of the species under some circumstances. In summary, Heterozygous effect is the key reason for the formation of biodiversity on the earth.
