Chromosome duplications and deletions frequently result in abnormal phenotypes or inviable gametes. Which factor is a major cont

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.

do members of the same phylum share more characteristics than members of the same class? Explain why or why not.

SVEN [57.7K]

Answer: No, they don't.

Explanation:

In the taxonomic rank (Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species-- in that order) because phylum comes before class, it means it covers a broader spectrum of organisms. So, the traits are less specific. As you narrow it down, the members of the rank will share more and more traits in common.

Here is an example:

Humans are a member of the phylum chordata. All members of phylum chordata share the same 5 traits at some point in their lifetime. (Some only show the traits when they are embryos/larvae). These 5 characteristics share a tail, a notochord, a single, hollow nerve cord, pharyngeal slits, and an endostyle (thyroid).

So, now that we've established that humans are from phylum chordata, we can narrow it down to what class they are in. Humans are in the class mammalia, meaning they are mammals. All mammals not only share those 5 characteristics of phylum chordata, but they also share characteristics that unite them with each other. They all have hair, mammary glands in females, and are endothermic.

So, while members of the phylum chordata share at least 5 traits, members of the class mammalia share at least 8.

I hope that makes sense!
