Question

______ mutations originate during meiosis while ______ mutation originates during mitosis.

  1. Germinal, somatic

  2. Germinal, spontaneous

  3. Spontaneous, point

  4. Somatic, germinal

hintHint:

Somatic mutation occurs during zygote formation.

The correct answer is:

Germinal, somatic


    • Gene mutations that occur in sex cells are called germline mutations. These mutations occur in meiosis, affect all cells in an individual, and pass the mutations on to the next generation.
    • We are talking about somatic mutations when the mutation occurs in another somatic cell.
    • Somatic mutations arise after zygotogenesis and are present in clones of cells in one or more tissues of the body as they reflect random mutations during normal mitotic cell division of embryonic development.
