Genetics Review

Heredity is the passage of instructions from one generation to the next. Which of the following is NOT an example of these genetic instructions in humans?

• Height

• Skin Color

• Dimples

• Spoken Language

What would be a possible disadvantage of asexual reproduction?

• Ability to reproduce in the absence of a mate

• Results in low genetic variation in the offspring

• Takes less time to produce offspring

The amoeba is a unicellular organism. It reproduces asexually through a process known as binary fission. The cell divides into two separate cells, the parent cell and the new cell. According to this information, which of the following statements best describes the new amoeba cell?

• The new amoeba cell only contains half of the genetic material from the parent amoeba cell

• The new amoeba cell is a different species than the parent amoeba cell

• The new amoeba cell received half of its genetic material from each parent

• The new amoeba cell is genetically identical to the parent amoeba cell

Which of the following is NOT an example of heredity?

• Lions showing their cubs how to hunt for prey

• Bacteria reproduce asexually to create cells identical to their parent cell

• A boy, whos is 5ft, 10 inches, is taller than his father who is 5ft, 8 inches.

• A red geranium plant is bred with a white geranium plant which produces a pink geranium.
