| homeotic gene | <molecular biology> Gene, containing homeobox, the level of expression of which is set during embryongenesis in response to positional cues and which then directs the later formation of tissues and appendages appropriate to that part of the organism. Mutation of these genes leads to inappropriate expression of characteristics normally associated with another part of the organism (homeotic mutants. (18 Nov 1997) |
| homeotic genes | A group of genes that regulate the development of the body parts by defining the boundaries of the several regions. (05 Mar 2000) |
| homeotic mutant | <molecular biology> A mutant in which one body part, organ or tissue, is transformed into another part normally associated with another segment. Examples are the antennapedia and bithorax mutants of Drosophila. (18 Nov 1997) |
| homeotic mutation | <embryology, genetics> A mutation that causes an organism to develop a homologous body part or structure in place of the part or structure that should normally be there (for example, developing a hand in place of a foot). (09 Oct 1997) |
| homeotic selector gene | <molecular biology> The genes in the fruit fly Drosophila which code for the segmentation of the thorax (the bithorax complex) and the limbs and appendages, such as antennae and legs (antennapedia complex). (09 Oct 1997) |
