Explain how genetic variation is achieved in sexual reproduction and why it is beneficial for a species' survival.

• Genetic variation is achieved through mitosis, which creates identical cells, and it is beneficial because it maintains uniformity.

• Genetic variation is achieved through meiosis and fertilization, which shuffle genes, and it is beneficial because it increases adaptability to changing environments.

• Genetic variation is achieved through binary fission, which creates clones, and it is beneficial because it ensures consistency.

• Genetic variation is achieved through budding, which produces identical offspring, and it is beneficial because it simplifies reproduction.

Which of the following best describes the role of meiosis in sexual reproduction?

• Meiosis produces identical cells that are used for growth and repair.

• Meiosis is a process that occurs only in asexual reproduction.

• Meiosis reduces the chromosome number by half, creating gametes that contribute to genetic diversity.

• Meiosis results in the production of two identical daughter cells.

Which of the following best describes the genes of offspring of organisms that reproduce sexually?

• The genes of each offspring are identical to that of every other offspring.

• Each offspring receives genes that are identical to one, and only one, of the parents.

• The genes of each offspring are unique and do not resemble those of either parent.

• Every offspring has genes that are a combination of the genes of each parent.

Which of the following best describes the difference in the results of mitosis and meiosis?

• Mitosis results in daughter cells with a complete set of genes. Meiosis results in daughter cells with half the genes.

• Mitosis results in four or more daughter cells. Meiosis results in only two daughter cells.

• Mitosis produces results in only a few seconds. Meiosis produces results in several hours.

• Mitosis results in daughter cells with a cell membrane. Meiosis results in daughter cells with a cell wall.

An organism is living in a rapidly changing environment. For an organism in this situation, sexual reproduction is advantageous because–

• it produces more offspring than asexual reproduction within a given period.

• the offspring are different from the parents, and some may be better adapted.

• 
  it requires more time to complete, allowing the environment to become more stable.

• the offspring grow to maturity more rapidly.

During meiosis, genetic recombination occurs because–

• 
  chromosomes assort independently, and crossing-over occurs.

• genes from different species can freely mix together.

• gene mutations occur more frequently than at other times.

• 
  cells divide into only one, resulting in genetically identical cells.
