Answer:

Genes coding for proteins involved in chiasma formation.

Explanation:

Chiasma is the connecting link between two non sister chromatids from homologous chromosomes. At chiasma chromosomal crossover takes place in which the genetic material is exchanged between the chromatids. During meiosis aneuploidy occurs if chiasma is absent or impaired due to a mutation in genes encoding for proteins involved in chiasma formation.

Aneuploidy is characterised by presence of abnormal number of chromosomes in cells. They can be 45 or 47 in number apart from the usual 46. Due to impaired chiasma, chromosome pair fails to separate and is passed on to the egg or sperm as it is hence there is one gamete with an extra chromosome and one gamete with a less chromosome. Aneuploidy can result in many genetic disorders like three copies of chromosome 21 can result in Down syndrome.

Roman55 [17]
The cranial nerve most likely to be affected hat is evidenced by acute labyrinthitis is the EIGHTH Cranial Nerve named Vestibulocochlear.

Vestibulocochlear nerve dysfunction can cause hearing loss, vertigo, or tinnitus. The dysfunction is a result of the damage in either the cochlear or vestibular portion of the eighth cranial nerve. Damage is  between the inner ear and its entry into the brainstem at the pontomedullary junction.

Vestibular neuritis is also identified as labyrinthitis, vestibular neuronitis, and acute peripheral vestibulopathy.

ki77a [65]
Water is essential to life because it creates us humans, plants, animals, etc. So, if we find water on Mars it would be important because water is essential to life, meaning we would know that there would be some kind of life on Mars because water makes up anything.
