Somatic cells are body cells. They use __________ to reproduce.

• mitosis

• meiosis

• crossing over

• nondisjunction

Gametes are sex cells. What process produces gametes?

• mitosis

• meiosis

• fertilization

• differentiation

Only mutations in gametes, or sex cells will be passed to offspring. Which of the following is a gamete?

• sperm cell

• skin cell

• lung cell

• liver cell

How is asexual reproduction different from sexual reproduction?

• asexual organisms produce offspring that are identical, sexual organisms produce offspring with genetic variation.

• sexual organisms produce offspring that are identical,asexual organisms produce offspring with genetic variation.

• both processes produce genetically varied offspring.

• both processes produce identical offspring.

Which of the following is an advantage of sexual reproduction?

• genetic variation

• needing a partner

• increased reproduction time

• producing identical clones

Nondisjunction is....

• the failure of homologous chromosomes or sister chromatids to separate during meiosis, results in gametes with extra and missing chromosomes

• The random alignment of maternal and paternal chromosomes at the metaphase plate

• the replication of DNA

• the splitting of cytoplasm between daughter cells

How does crossing over contribute to genetic variation?

• forms new combinations of gene in chromosomes

• results in extra chromosomes in gametes

• breaks down the nuclear membrane during prophase

• moves sister chromatids to opposite poles of the cell

how many nuclear divisions occur during meiosis?

• 2

• 1

• 4
