Oraciones de ejemplo
- Genes identified by such mutations are called homeotic genes because when mutated they result in homeosis - the transformation of a whole segment or structure into another related one, as in the transformation of antenna to leg.
- This research on homeosis was intended to support both his view of genetic structure and his view of evolution.
- However, those experiments show only what morphological changes are possible to manipulate experimentally, not what actually happened in evolution, and one question is why homeosis would occur at all.
late 19th century: from Greek homoiōsis 'becoming like', from homoios 'like'.
- Oraciones de ejemplo
- The evolution of homeotic mutants, according to Simpson, still depended on selection acting on populations of individuals.
- Thus major changes in body plan are possible over very short time intervals when homeotic, regulatory genes are involved.
- For example, it is becoming clear that co-option has played a critical role in evolution and the homeotic genes are not exempt in this regard.
