What is the difference between a single gene disorder, multifactorial disorder and a chromosomal abnormality?

1 answer:

5 0

There are approximately 25,000 genes contained on the 46 chromosomes in each cell of the human body. This means that one chromosome contains thousands of genes. A person can have normal chromosomes in number and structure, but still have a disease or condition caused by a mutation in one or more of the genes on the chromosomes. A single gene defect usually does not cause the chromosome structure or number to be abnormal. Similarly, a person can have normal genes; however, if the person has extra copies of genes due to a chromosome abnormality, then those extra copies can cause the genes to not work properly.

Answer:

A feline skeletal muscle cell undergoes cell division, resulting in two feline skeletal muscle cells.

Explanation:

We are looking for a parent cell that gives rise to daughter cells with identical genetic information.

In simpler words, we are looking for something that makes 'clones' of itself.

In this statement (second option), the parent and daughters are all feline skeletal muscle cells.

A feline skeletal muscle cell undergoes cell division, resulting in two feline skeletal muscle cells.

Other incorrect choices: (All having to do with reproduction).

A child has brown eyes; one of its biological parents has green eyes, and the other has brown eyes.

This situation has two parents, each with a different trait. The child takes one of the parent's trait. The parents did not make a 'clone' of themselves.

A human sperm fuses with a human egg cell, resulting in the development of a new human.

The parents don't make 'clones' of themselves. The sperm did not make more sperm. The egg did not make more egg cells.

A long-stemmed plant reproduces with a short-stemmed plant, and the offspring are all long-stemmed.

The offspring plant only took the trait from one of it's parents. Also, whole plants are not individual cells.
