Answer:

The phenomenon of unequal separation in meiosis is called nondisjunction. If nondisjunction causes a missing chromosome in a haploid gamete, the diploid zygote it forms with another gamete will contain only one copy of that chromosome from the other parent, a condition known as monosomy. I think sorry if wrong ;)

Compare and contrast the five layers that make up the atmosphere.

Wittaler [7]

Exosphere is in the top 600-800km exosphere has a very low amount of gases almost like in outer space.

Termosphere, 80-600km absorbs gamma rays uv rays and rays that damage our healt also know as ionosphere, is the hottest one.

Mesosphere, 50-80km, the temperature here reaches -140 Celsius shooting stars are formed here

Stratosphere, 12-50km produces the mayor part of the atmospheric ozone, some army planes reach this later

Troposphere, thats the source of the mayor part of the gases here in the atmosphere.

kherson [118]

Chromosome duplications and deletions frequently result in abnormal phenotypes or inviable gametes. Gene dosage is modified is a major contributor to this phenomenon.

In the field of genetics, we can define gene dosage as the quantitative measure or copies of a particular gene that is present in an organism. Abnormalities in the gene dosage at a particular location can cause severe damage to the resulting phenotype.

Gene dosage can lead to chromosome duplications if the copy number or gene product is more and it can cause deletions if the copy number or gene product is less. Such complications will result in abnormal phenotypes or inviable gametes. For example, in Down's syndrome, the person has a modification of the 21st chromosome as there is one extra 21st chromosome present. This leads to a variety of diseases and defects in the person.

Although a part of your question is missing, you might be referring to this question:

Chromosome duplications and deletions frequently result in abnormal phenotypes or inviable gametes. Which factor is a major contributor to this phenomenon?

a. Recessive diseases are unmasked by additional copies.

b. The genes are found in a novel arrangement.

c. Gene dosage is modified.
