Duplicated genes

WebJun 26, 2024 · Genome duplication generates an extra copy of nearly all genes carried by an organism, providing a potential substrate for evolution. Although many duplicate genes will be eliminated after a genome duplication, those that are retained may evolve distinct functions over time. WebWe even have a name for that - heterosis. This is (most likely) because two pure strains have no duplicate junk genes while having more genetic adaptability (in simpler terms - more genes for different situations) Even in second generation (F2 in biology) this effect drops completely. But, remember, we were talking about same-species hybrids.
