Section: Mutation and Genetic Change
Read the passage below. Then answer the questions that follow.
Multicellular eukaryotes have two major cell types: germ cells and
somatic cells. Germ cells makeup the gametes, whereas somatic
cells make up the rest of the body. Mutations can occur in either
type of cell. However, if a mutation occurs in a somatic cell, that
genetic change will not affect the person's future offspring. For
example, a mutation in a person's lung cell could cause the cell to
grow into lung cancer. Yet, the mutated genes in the cancer cells
will not be transferred to the person's children.
Only a mutation in a germ cell may be passed on to the next
generation. However, any such mutation may be silent and have
little effect. Only rarely do mutations cause significant changes in
future generations.

One parent cell undergoes mitosis, which results in the division of two identical daughter cells.
Definition of primal
Mitosis is the mechanism of reproduction in unicellular eukaryotes.
For eukaryotes with many cells:
Mitosis boosts cell production and promotes bodily growth and development.Damaged tissues or organs can be
repaired by mitosis.Mitosis is a kind of reproduction for vegetative organisms that results in offspring with the same
genotype as the parent.
