Which best describes genetic mutations? Some inherited genetic mutations can be good for the offspring. Different genetic mutations cause few forms of cancer. Somatic mutations can be inherited from parents or acquired during life. Genetic mutations that cause diseases are always passed on to offspring.



Answer :

The answer is: Some inherited genetic mutations can be good for the offspring.

Problems with the other answers:
Different genetic mutations cause many forms of cancer.

Somatic mutations can be acquired during life, but cannot be inherited from parents. Germ cell mutations can be inherited from parents or acquired during life.

Genetic mutations that cause diseases are not always passed on to offspring. For example, it could be a somatic mutation (soma = body, other than reproductive cells), and this would not be the genetic material passed on in the sperm or ova. Also, by chance the child may receive the non-mutated allele from the parent. Or in the case of X linked diseases, perhaps the father has an X linked recessive disease, but will not pass his X chromosome to his son, he will pass his Y chromosome, etc.

The correct option is some inherited genetic mutation can be good for the offspring.

Further Explanation:

The change in the sequences of deoxyribonucleic acid (DNA) is known as mutation. It can occur due to mistakes while making a copy of deoxyribonucleic acid (DNA) or due to some environmental factors. At the time of replication, the alteration can occur in the sequences of deoxyribonucleic acid which results in mutations.

Hereditary mutation is the mutation which leads to evolution as mutation occurs in germ cells. This type of mutation can pass from one generation to another. These mutations are inherited from parents.

Genetic mutations which are inherited from parents to offspring can be good as it leads to evolution. Genetic recombination or gene mutation can lead to genetic variation that is the difference in sequences of deoxyribonucleic acid between individuals of the same population.
