MUTATIONS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In which types of cells must mutations occur in order for the mutation to be passed-on to future generations?
A
Somatic cells
B
Genes
C
Gametes
D
Alleles
Explanation: 

Detailed explanation-1: -Mutations can occur in either cell type. If a gene is altered in a germ cell, the mutation is termed a germinal mutation. Because germ cells give rise to gametes, some gamete s will carry the mutation and it will be passed on to the next generation when the individual successfully mates.

Detailed explanation-2: -The only mutations that matter to large-scale evolution are those that can be passed on to offspring. These occur in reproductive cells like eggs and sperm and are called germ line mutations.

Detailed explanation-3: -If a parent carries a gene mutation in their egg or sperm, it can pass to their child. These hereditary (or inherited) mutations are in almost every cell of the person’s body throughout their life. Hereditary mutations include cystic fibrosis, hemophilia, and sickle cell disease.

Detailed explanation-4: -Germline mutations occur in a parent’s reproductive cells (egg or sperm). These mutations change the genetic material that the child receives from their parent (hereditary).
