Those mutated genes are most commonly recessive. Females have two X chromosomes so they can have a chromosome with the mutated gene and one with the healthy gene. The healthy gene is dominant so the disease won't manifest, and the woman is only a carrier. Males have only one X chromosome and an Y chromosome. If they have the mutated gene on the X chromosome they won't have another X chromosome with the healthy gene.

To summarize, men can't be carriers and they only need one copy of the mutated X-linked gene while women need two copies of the mutated gene.

Vadim26 [7]

Answer:

Drive-reduction theory

Explanation:

Drive reduction theory is a motivation theory which is based on the principle that organisms are born with certain psychological needs and that they experiment a state of tension when these needs are not satisfied.

This state of tension pushes them to find a way to satisfy those needs, and when those needs are satisfied again, drive is reduced and the person returns to a state of homeostasis and relaxation.

According to this theory, motivation happens when we experiment the state of tension and it's this motivation that drives us to satisfy our needs and be able to feel better.

Dr. Williams is a psychologist who believes that motivation is produced when we feel an uncomfortable internal state that pushes us to find a way to feel better.

In this case, Dr. Williams thinks that our motivation originates from an uncomfortable state (state of tension) that pushes us to find a way to feel better (in order to reduce the drive and be back to homeostasis).

We can observe that Dr. Williams belief is very similar to the drive-reduction theory.

Note:

a) Incentive theories of motivation state that people are motivated by incentives that are given to them (either internally or externally) when they do a expected behavior.

b) Maslow's hierarchy of needs states that our needs are based on a hierarchy in form of pyramid in which we first need to satisfy the needs at the bottom (physiological needs) to be able to proceed with the other needs that are higher on the hierarchy until we reach the self-fulfillment needs.

d) Instinct theory states that we are driven by instinct that we need to satisfy in order to experience balance and homeostasis.
