The arrangement of homeotic genes along chromosomes of vertebrate and invertebrate animals corresponds to the expression pattern of the genes along the __________ axis of the developing embryo

Respuesta :

The arrangement of homeotic genes along chromosomes of vertebrate and invertebrate animals corresponds to the expression pattern of the genes along the anterior-posterior axis of the developing embryo.

What are homeotic genes?

  • Homeotic genes are a group of body pattern forming genes which control the development along the anterior- posterior axis of the developing embryo.
  • These encode transcription factors which control and specify the genes involved in body patterning. These provide identity to the segments during embryo formation.
  • Genes located in the 5’ end act on posterior side whereas the genes on 3’ end act on anterior region.
  • Homeotic genes are evolutionary conserved and control body specification, patterning and differentiation.
  • The loss of function of any of the gene changes the body pattern and affects the development.
