Acromegaly is a hormonal disorder that develops when the pituitary gland secretes too much growth hormone during adulthood. When such condition happens, the bones will increase in size including the hands, feet and face. 

To be able to diagnose acromegaly, two key blood tests should be performed: one for insulin-like growth factor-1 (IGF-1) and an oral glucose tolerance test (OGTT). There is also an imaging test to confirm acromegaly and that is through magnetic resonance imaging (MRI) scan of the pituitary gland.

Insuline-like growth factor-1 is a hormone that is closely knitted to growth hormone.  To determine if a person has acromegaly, even if he has high levels of IGF-1, his body continuously produces growth hormones. It must be noted that IGF-1 signals the body to stop producing growth hormones. Thus, an elevated IGF-1 level may indicate acromegaly.

Acromegaly is the medical term used to describe the abnormal growth of the hands, feet and face. It is caused by the overproduction of growth hormones by the pituitary gland.

If a person is suspected to have acromegaly, the best way to confirm it is through two key blood testing: 1. to check the level of the insulin-like growth factor-1 (IGF-1); and 2. an oral glucose tolerance test (OGTT).

Imagine that individuals with a certain allele (B) have much greater reproductive success than those without the allele. However
Sonbull [250]
<h2>Allelic frequency </h2>

Explanation:

The B allele will become more common only if the individuals reach reproductive ages

Since the individuals with allele B have much greater reproductive success therefore once they reach the reproductive age, success to reproduce new individuals will be higher

The offsprings will carry on the allele(B allele) and pass on to the next generation

Even if the parental individuals die because of shorter life span the offsprings produced in each generation will pass on the allele to their subsequent generation

In cats, the gene for Calico (multicolored) cats is an x-linked trait that is
hichkok12 [17]

Answer:

Considering the <u>whole progeny</u> (100%), there will be

  • 25% Black male kittens, XBY
  • 0% Calico Male kittens
  • 25% Calico female kittens, XBXR

Explanation:

<u>Available data:</u>

  • The gene for Calico (multicolored) cats is an x-linked trait and codominant
  • Calico Females receive a "B" and an "R" gene, and have black and orange splotches on white coats. Their genotype is XBXR.
  • Males can only be black or orange, but never calico. Their genotype is XBY and XRY

Cross: a female calico cat with a black male

Parentals)   XBXR    x    XBY

Gametes)  XB  XR       XB   Y

Punnett square)    XB        XR

                   XB   XBXB   XBXR

                    Y      XBY      XRY  

F1) Among the whole progeny:

  •     2/4 = 50%  will be black (female XBXB and male XBY)
  •     1/4  = 25% will be Calico (female XBXR)
  •     1/4  = 25% will be Orange (male XRY)  

   Among females:

  •    1/2 = 50% of females will be black, XBXB
  •    1/2 = 50% of females will be Calico, XBXR

   Among males:

  •    1/2 = 50% of males will be black, XBY
  •    1/2 = 50% of males will be orange, XRY
