DNA Reproduction Review

Which of the following is a disadvantage for sexual reproduction

• The genetic diversity makes organisms respond differently to environmental changes

• Offspring can be produced more quickly than by asexual mean

• A lot of time and energy is required for making gametes and finding mates

• The offspring are genetically different.

Which of these statements is true of asexual reproduction?

• It produces offspring genetically identical to each other and requires one parent

• It produces offspring genetically identical to each other and requires two parents

• It produces offspring genetically different from each other and requires one parent

• it produces offspring genetically different from each other and requires two parents.

Which of these statements correctly describes a difference between asexual and sexual reproduction?

• Asexual reproduction increases genetic diversity, but sexual reproduction does not

• Asexual reproduction involves one parent, and sexual reproduction involves two parents

• Asexual reproduction increases a species’ chances of surviving unfavorable conditions, but sexual reproduction does not

• The offspring produced by asexual reproduction are not identical to each other, but those of sexual reproduction are identical to each other

What results from asexual reproduction?

• offspring that are genetically identical to the parent

• offspring that are genetically different from each other

• offspring that are genetically different from the parent

• offspring that are genetically identical to similar species

Which of the cells above went through mitosis and which went through meiosis?

• Cell A went through mitosis and Cell B went through meiosis

• Cell A meiosis went through and Cell B went through mitosis

• Both Cell A and Cell B went through meiosis

• Neither cells through meiosis and mitosis

During class, Julia takes notes about what happens to genetic material during cell division. After class, she draws an illustration to accompany her notes. Her illustration is similar to the one shown.

What label should Julia use at position Z in the diagram?

• chromatin

• chromosome

• DNA

• protein

What is the result of mitosis?

• two new cells

• two new nuclei

• two new copies of DNA

• two new pairs of chromosomes

A Chromosome is best described as a:

• Gene that has more than one type

• A coiled strand of DNA containing genetic information

• Green cell found in many plants

• Reproductive cell found in bacteria

What process creates two identical cells?

• Mitosis

• Asexual Reproduction

• Sexual Reproduction

• Meiosis

Which of these statements is true of sexual reproduction?

• It requires two parents and results in offspring that have characteristics of each parent

• It requires one parent and results in offspring that are genetically identical to the parent.

• It requires two parents and results in offspring that are genetically identical to one parent

• It requires one parent and results in offspring that have half of the genes of the parent
