Bio Test #1 & #2 Review

Some organisms are descended from only 1 parent. What is the name for this type of reproduction?

• Asexual reproduction

• Sexual reproduction

• Singular production

• Monoproduction

Which form of cell division plays a key role in sexual reproduction?

• Mitosis

• Budding

• Meiosis

• Conjugation

Offspring that are produced through sexual reproduction are usually similar, but never identical, to their parents. This is because:

• Half of the offspring's genes come from one parent while the other half comes from the other parent.

• Genes are not transferred between parents and offspring during sexual reproduction.

• All of the offspring's genes only come from one parent or the other.

• Genes mutate during every occurrence of sexual reproduction.

Select the choice that best completes the following sentence:

Asexual reproduction produces offspring that are genetically __________ to the parent.

• identical

• unrelated

• similar

• opposite

Select the choice that best completes the following sentence:

_______ reproduction requires one parent, while _______ reproduction requires two parents.

• Animal, bacterial

• Sexual, asexual

• Single, double

• Asexual, sexual

A human body cell has 46 chromosomes. How many chromosomes does a human egg or sperm cell have?

• 92

• 46

• 23

• 0

The offspring of a sexually reproducing organism receives

• an exact copy of one parent's genetic material.

• genetic material that is not related to either parent.

• an exact copy of each parent's genetic material.

• half of its genetic material from each parent.

Mitosis is a type of cell division that produces cells that are used for growth and repair. Meiosis is a different type of cell division that produces sex cells used for sexual reproduction.

Based on the information provided, which of the following is a difference between mitosis and meiosis?

• Mitosis produces cells that carry twice as much genetic material as the parent cell, while meiosis produces cells that identical to the parent cell.

• Mitosis produces cells that carry half of the genetic material of the parent cell, while meiosis produces cells that are identical to the parent cell.

• Mitosis produces cells that are identical to the parent cell, while meiosis produces cells that carry half of the genetic material of the parent cell.

• Mitosis produces cells that are identical to the parent cell, while meiosis produces cells that carry twice as much genetic material as the parent cell.

Which is an advantage of sexual reproduction over asexual reproduction?

• Sexual reproduction produces more diversity.

• Sexual reproduction produces more offspring.

• Sexual reproduction never produces genetic defects.

• Sexual reproduction is quicker and less complex.

Which of the following is a characteristic of meiosis but not of mitosis?

• produces four daughter cells

• involves only one cell division

• separates one existing cell into two identical new cells

• involves only single-celled organisms
