A) In the Dunker population, the frequency of IB allele is 0.3 and the frequency of i allele is 0.4. In the general population, the frequency of IB allele is 0.1 and the frequency of i allele is 0.5.

If:
$I^{A}$ - the frequency of IA allele
 $I^{B}$ - the frequency of IB allele
 $i$ - the frequency of i allele

Then:
 $I^{A} I^{A}$ + $I^{A} i$ - the frequency of individuals with A blood type
 $I^{B} I^{B}$ + $I^{B} i$ - the frequency of individuals with B blood type
 $ii$ - the frequency of individuals with O blood type

Let's first take a look on the Dunker population:
$I^{A} = 0.3$
$ii=0.16
$

Since there is only one possible genotype for O individuals - ii - the frequency of the allele i is square root of the frequency of O individuals:
 $i= \sqrt{ii}$
⇒ $i = \sqrt{0.16}$
⇒ $i=0.4$

Now, we have the frequencies of two alleles ( $I^{A}$ and $i$ ). To calculate the frequency of $I^{B}$ allele, we will use the formula:
 $I^{A} + I^{B} + i = 1$
⇒ $I^{B} = 1- I^{A} - i$
⇒ $I^{B} = 1-0.3-0.4$
⇒ $I^{B} = 0.3$

Now, in the general population:
$I^{A} = 0.4$
$ii=0.25$

Similarly to the work for the Dunker population:
 $i= \sqrt{ii}$
⇒ $i = \sqrt{0.25}$
⇒ $i=0.5$

$I^{A} + I^{B} + i = 1$
⇒ $I^{B} = 1- I^{A} - i$
⇒ $I^{B} = 1-0.4-0.5$
⇒ $I^{B} = 0.1$


b) A founder effect is a result of geographical separation of a few individuals from the original population. Those founding individuals will form a new population. The Dunker population was not only geographically separated, but also genetically. The group interbreeding was present resulting in increasing those allele frequencies that were the most common in the founding population. In this case, the most individuals from the founding population had B blood type.

What problems might result from the prolonged administration of cortisol to a person with severe inflammatory disease?

ki77a [65]

Answer:

The prolonged exposure to cortisol hormone may cause different health problems including anxiety, depression, muscle atrophy, hypertension, metabolic problems, diabetes, myopathies, osteoporosis, etc.

Explanation:

Cortisol is a stress hormone secreted by the adrenal glands, it is a steroid hormone that is involved in diverse functions including the control of metabolic and immune responses, salt balance (blood pressure), etc. Moreover, cortisol hormone also has anti-inflammatory properties. However, prolonged exposure to stress hormones like cortisol is associated with different health problems, especially anxiety and depression.

Which disorder, diagnosed in the 1800s, was believed to be caused by a woman experiencing "wandering movements of the womb"?

HACTEHA [7]

A 2nd-century hysteria was caused by the belief that the uterus could move freely within the body in search of fluid and cause specific symptoms depending on the areas the uterus was displaced to. Called the wandering womb disorder, the womb was believed to be a living thing within a living thing.
