Why is it important for organisms to have a set of instructions (DNA) that determines their traits and allows heredity from one generation to another?

Multiple Select

Select all that apply: Which of the following are functions of mitosis in multicellular organisms?

• Growth

• Repair of tissues

Explain why it is important for cells to have a half set of DNA after meiosis.

Multiple Choice

Which statement best describes homologous chromosomes in adult body cells?

• They are identical copies from one parent.

• They are matching chromosomes, one set from each parent.

• They contain only genes from the female parent.

• They contain only genes from the male parent.

Multiple Select

Which of the following are true about the process of meiosis?

• It occurs in sex organs only.

• It produces daughter cells with half the chromosome number of the parent cell.

• It produces identical cells to the parent cell.

• It occurs in both plants and animals.

Open Ended

Explain what would happen to the chromosome number in humans if meiosis did not occur during the formation of sex cells.

Multiple Select

Select all correct statements about the role of meiosis in maintaining chromosome number across generations.

• Meiosis reduces chromosome number in sex cells.

• Without meiosis, chromosome number would double each generation.

• Meiosis ensures offspring have the same chromosome number as parents.
