A (n) <u>homeotic</u> gene is a type of gene that regulates development and that, when mutated, leads to organisms with structures in abnormal or unusual locations on their body.
A homeotic gene is a gene that intervenes in the developmental program that determines the location of structures along the anteroposterior axis.
- The determination of the anteroposterior axis is one of the earliest events in development, and it guides the remaining processes of organogenesis.
- Once homeotic genes define the identity of the body segments, they code for proteins (homeodomain) that are responsible for activating other genes.
- These genes ultimately trigger the formation of the organs or limbs of this segment.
- Genes that control the position of organs have been called homeotic genes, while mutations that affect these genes are known as homeotic mutations.
Therefore, we can conclude that homeotic genes are expressed in the body regions that will house the growing structures.

Answer:
Secondary waves are also called S waves. As they pass through a material, the material's particles are shaken up and down or from side to side. Secondary waves rock small buildings back and forth as they pass. Secondary waves can travel through rock, but unlike primary waves they cannot travel through liquids or gases.
Explanation:
Therefore, it must be useable which means Plants and animals have a connection between living. Animals eat plants, some do, like herbivores.
The CEREBRUM is responsible for those functions
Embryonic cells that are called totipotent are the ones that could give rise by itself to the entire embryo. Totipotency is an ability of a cell to produce and divide all differentiated cells in a living organism. Hope this answers the question.
