Definition of homeotic in English:


(British homoeotic)


  • See homeosis

    • ‘Sundberg interpreted many aspects of trilobite evolution in terms of homeotic change.’
    • ‘Thus major changes in body plan are possible over very short time intervals when homeotic, regulatory genes are involved.’
    • ‘These genes encode proteins that are involved in regulating the expression of homeotic genes by changing chromatin structure.’
    • ‘The evolution of homeotic mutants, according to Simpson, still depended on selection acting on populations of individuals.’
    • ‘Several genes involved in the regulation of chromatin structure were identified as regulators of homeotic gene complexes.’
    • ‘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.’
