7.L.2.1

Why is approximately 50% of any individual’s DNA inherited from that individual’s father?

• It was passed to the individual by a gamete from the father.

• It was passed to the individual by a somatic cell from the

  father.

• The father copies half of the cells in his body and passes

  them to their child.

• The father’s nucleus splits over and over but stops when it reaches half

What types of cells are found only in organisms that reproduce sexually?

• Blood cells

• Skin cells

• Neurons

• Gametes

Mitosis and meiosis are similar processes. Which best describes what can only occur after meiosis?

• Two daughter cells are produced

• Three daughter cells are produced

• No daughter cells are produced

• Four daughter cells are produced

Potatoes reproduce by growing sprouts on their surfaces as shown. When planted, these sprouts grow into new plants. This is an example of

• Sexual Reproduction

• Asexual Reproduction

• Fertilization

• Seed production

Which is the greatest benefit of sexual reproduction?

• capable of reproducing through meiosis

• ability to reproduce without a mate

• ability to produce genetically different offspring

• capable of producing offspring genetically identical to parent

A human body cell has 46 chromosomes. Which diagram

represents mitosis in a human body cell?

• 
• 
• 
• 

Why does sexual reproduction result in more genetic diversity than asexual reproduction?

• Genes from two parents are combined

• More organisms reproduce this way

• Offspring grow in different enviornments

• Offspring come from identical parents

What advantage do the offspring of a dandelion have by reproducing asexually?

• Reproduction occurs rapidly

• Reproductive competition is increased

• Mating compatability improves

• Diversity increases between generations

Some organisms reproduce sexually while other organisms reproduce asexually. Which would be an example of asexual reproduction?

• 
• 
• 
• 

Which statement describes a characteristic of both sexual and asexual reproduction?

• Two parents are required

• The processes produce genetically unique offspring

• The processes require egg cells

• New cells are produced
