What snakes and caecilians have in common? molecular interaction units and the independent origins of similar morphotypes in tetrapoda
Biological sciences; 289 (1981), 2022
ABSTRACT: Developmental pathways encompass transcription factors and cis-regulatory elements that interact as transcription factor-regulatory element (TF-RE) units. Independent origins of similar phenotypes likely involve changes in different parts of these units, a hypothesis promisingly tested addressi...
