Answer: 10. Control Group

11. Identify the:

Control Group = Subject A

Independent Variable = The new and original itching powder.

Dependent Variable = The type of itchiness.

Explanation: The Control Group is NOT affected by the experiment. Subject A was given the original itching powder and is not being experimented on with the new itching powder, therefore, Subject A is the Control Group.

The Independent Variable is what you can CHANGE. You control the two itching powders, so you decide which one you give to who. This makes the two itching powders the Independent Variable.

The Dependent Variable DEPENDS on the effects of the Independent Variable. This is what you cannot change, the results. In this case, the type of itchiness experienced and the amount of itchiness experienced cannot be changed, it is a result of the powders, hence why it is the Dependent Variable.

torisob [31]

This can be solved with Punnett squares. The affected male has the $X^{B} y$ genotype, and the female is homozygous recessive. This means that she does not carry this, and therefore, will have the genotype XᵇXᵇ

While doing this Punnett Square, keep in mind that in order to have the male offspring affected, their genotype has to be $X^{B} y$

Since there are no $X^{B} y$ , the probability of their male offspring inheriting this disease is 0%
