Question

Based on what you've learned, briefly explain the evolutionary significance of the fact that parents pass on their chromosomes to their children. what happens when there is an error in the mechanisms by which chromosomes are passed down? what are some genetic disorders that can arise from mutations that are either inherited or acquired?
a sample answer might look like this: parents pass on their chromosomes to their children because the dna, packaged in the chromosomes, provides the instructions for all cells in the body to function. if there is an error in the mechanisms by which chromosomes are passed down, the chromosomes may not be passed down properly. this could lead to genetic disorders. there are many examples of genetic disorders that range from very minor to very severe. a frameshift mutation causes tay-sachs disease, an autosomal recessive disorder that is typically fatal. frameshift mutations, in which the dna or rna sequence's reading frame is shifted by the addition or deletion of nucleotides, can have catastrophic consequences.

Answer 1

Gene mutations can be classified in two major ways:  These mutations are also called germline mutations because they are present in the parent's egg or sperm cells, which are also called germ cells. When an egg and a sperm cell unite, the resulting fertilized egg cell receives DNA from both parents.

The error takes place when the genes are copied and chromosomes are divided. They can lead to genetic disorders that are inherited.

What is gene mutation?

The mutation of the gene is the change in one or more genes that can lead to genetic disorders or illness. The gene disorders are classified in the 2 ways as germline mutations which are present in the parent's cells and are called germ cells. That can take place when the egg of the parent cell and the DNA unit.
