A student draws a Punnett square where two parents that are heterozygous for dimples are crossed. Dimples (D) are dominant to no dimples (d).

Using the Punnett square, what is the percent chance that the offspring will have dimples?

• 25%

• 50%

• 75%

• 100%

Sickle-cell anemia is caused by the homozygous recessive genotype. People with sickle-cell anemia have the genotype aa. People without sickle-cell anemia have either the genotype AA or Aa. A woman with the genotype AA has a child with a man with the genotype aa. What is the probability that their child will have sickle cell anemia?

• 0%

• 25%

• 50%

• 75%

• There is a 100% chance of having round, green peas.

• There is no chance of having any wrinkled, green peas.

• There is a 50% chance of having round, yellow peas.

• There is no chance of having any round, yellow peas.

A botanist crosses two pink-flowered plants. The cross is a case of intermediate inheritance that involves alleles that were not clearly dominant or recessive and could make red-, pink-, and white-flowered plants. If four plants are produced from the cross, what is the expected number of white-flowered plants?

• 0

• 1

• 2

• 3

The picture shows red blood cells in an isotonic solution.

Red blood cells have a semi-permeable membrane. Which will most likely occur if the red blood cells are placed in a hypertonic solution?

• The red blood cells will lose water and decrease in size.

• The red blood cells will absorb water and increase in size.

• The red blood cells will first absorb water, then lose water.

• The red blood cells will first lose water, then absorb water.
