What happens to an organism if they have a mutation in their hox gene?

∙ 10y ago
Morphological development is disrupted and the body plan, from dorsal to ventral and front to back, of the organism is not laid down properly. Mutations in the Hox genes of fruit flies are classic examples here. Legs growing where antenna ought to be and two headed embryos are usual examples of Hox gene mutation.

∙ 12y agoAccording to my research, Hox genes work by producing proteins that then bind to target gene enhancers who then "activate" genes to develop your body the way it needs to be. A Hox gene could change what type or how much protein it releases, meaning it could bind differently or to a different gene enhancer. Hox genes sometimes work together, meaning that even a small change could have major effects.

What are Hox genes?
Hox genes are a group of related genes that are specific for the anterior and posterior axis of an organism in embryonic development. They assist in the formation of segments in the developing animal.
What do homeotic genes direct?
A homeotic gene, known as a Hox gene controls the development of metazoa or animal body segments. An exaple of a homeotic mutation that occured in Drosophilia would be a leg developing where an antenna would normally be located.
What is the name of the series of genes that controls organs and tissues that develop in the embryo?
Hox genes (:
Why are hox genes found in different animals very similar to each other?
Hox genes in different animals are very similar to each other because they have very important functions during development: they tell each region of the embryo what kind of body segment to turn into. Think about what would happen to you if this process went wrong: your body parts wouldn't be in the right places, or you might be missing body parts altogether! It's therefore very important to keep these genes in working order, and that means not changing them too much. But how can essentially the same Hox gene be responsible for making head parts in a fly and head parts in a human, since our head parts don't look much alike? The answer is that Hox genes like to boss around other genes, and who they boss around can change. Hox genes tell a region of an embryo what to become by switching on certain subsets of genes and switching off other subsets. For example, in fruit flies, the Hox gene called Scr activates the subset of genes that turns cells into salivary glands. Also in fruit flies, the Hox gene Ubx turns off genes that activate wing development (so that wings do not develop). If these Hox genes are mutated to the point that they can no longer function, then the fly would have no salivary glands, and would have wings where it shouldn't! However, humans don't have wings, and our salivary glands are different from those of flies. Although we use essentially the same Hox genes, they've evolved to switch on or off different genes. In other words, the Hox Head Honcho is the same, but the employees are different.
The master gene Hox helps to sculpt the body plan of embryos by?
By turning on genes in the section of the embryo. For instance, in D. Melanogaster the head, thorax and abdomen all contain genes that give rise to brains, mouth and proboscis in the head region Wings in the thorax and legs there to. Spicules in the abdomen. Two sets of HOX genes control all this activity and are actually lined up linearly along the route of gene activity
What role do the hox genes play in the development of an organism?
Hox genes control the differentiation of cells and tissues in the embryo. A mutation of a hox gene can completely change the organs that develop in specific parts of the body.

What tells cells to differentiate during embryonic development?
The inheritance of an organism tells cells to differentiate during embryonic development.
What gene controls the expression of the D1x gene in vertebrates?
The HOX gene or the master gene of D1x
What is another word for Hox genes?
Hox genes are a type of homeotic gene. They can be called body plan genes.
Part of a strand of DNA with regulatory sequences?
hox gene
What is the hip-bone of a python an example of?
It is an example of something that doesn't exist. Or it could be an infinity unlikely retro mutation related to re-expression of the HOX gene pattern found in python's ancient ancestors, the lizards.
Differentiation of cells and tissues in the embryo is controlled by what?
hox gene (Yes i have e2020)

What is the importance of HOX genes. What do they determine?
Without Hox genes you'd be a very different looking person. They ensure that your head sits on the top of your body, that your feet are at the bottom, that your arms hang by your side and that your nose is in the center of your face. They are the pattern forming genes that guide body planning.
