Question

Quizplus · Accepted Answer

Homeotic genes are a group of genes that control the development of body structures in animals. They are responsible for determining the identity of different body parts, such as the head, thorax, and abdomen. More than one hundred homeotic genes have been identified, and they are found in all animals, from insects to humans. The same mechanisms control their transcription regardless of the species, and many of them are functionally interchangeable among species. Homeotic genes likely evolved in the most ancient eukaryotic cells, and they have played a key role in the evolution of animal body plans.
