Andre45 [30]

Behavioural genetics is the study of the effects of genes as well as well the environment on the behaviour of the individuals. The scientists who study the Behavioural genetics are known as behavioural geneticists.

In this case Dr. Hakim is studying the influence of genes and the environment on the aggression, which is a kind of behaviour. Hence, Dr. Hakim is a  behavioural geneticists, and he works in in the field of behavioural genetics.

Which of the following statements about aldosterone is NOT correct?
Olin [163]

Answer:

C. Aldosterone increases sodium reabsorption by increasing the number of Na+-K+ ATPase pumps in the luminal membrane of the proximal tubule.

Explanation:

  • Aldosterone hormone is produced by the adrenal gland and mainly carries out its functions in the kidney.Through the aldosterone hormone the body is able to retain more water for the kidney is able to hold more sodium.
  • When the plasma sodium levels decrease and the plasma potassium levels increase the production of aldosterone hormone is stimulated for sodium is needed in the .body to maintain the high water levels in the body.

Genetic drift simulation:
Airida [17]
Unlike natural selection, genetic drift does not depend on an allele's beneficial or harmful effects. Instead, drift changes allele frequencies purely by chance, as random subsets of individuals (and the gametes of those individuals) are sampled to produce the next generation.

Explain what it means for a section of DNA to be considered a molecular clock. Be sure to discuss the importance of neutral muta
IceJOKER [234]
  <span>Neutral mutations are neither harmful nor beneficial. 

Therefore, they are invisible to natural selection. (Since they neither improve nor worsen one individual's chances of survival and reproduction over another.) 

However neutral mutations can still spread into the population by just random replications and matings. This is called genetic drift. 

In other words, they are 'silent'. They are mutations that exist and propagate in populations, but seem to have no effect at all. 

The reason they can become important to evolution is that a day can come when they *do* have an effect. In other words, even though an individual mutation may have no immediate effect on survival or reproduction, a *combination* of neutral mutations may provide some new benefit or harm ... at which point natural selection *will* act on that combination.
