For people over 50, alcohol may positively affect the cardiovascular system by
White raven [17]

Alcohol may positively affect the cardiovascular system of people over 50 years old by reducing the risk of clot formation.

 

<span>Just like with the other body systems, excessive alcohol can have lethal effects on the cardiovascular system. Chronic alcohol use can upsurge the workload of the heart which can then lead to arrhythmia's or what is called an irregular heart beat, inflammation of the heart muscle or myocarditis, weakening of the heart muscle or cardiomyopathy, increased cholesterol, and even hypertension. Other problems are prominent with blood clotting and an increased workload of the heart that is linked to cirrhosis of the liver.</span>

In a cross between individuals of a species of tropical fish, all of the male offspring have long tail fins, and none of the fem
Sergio039 [100]

In this cross the trait of long tail fins is associated with the “Y” chromosome of the male.  

Thus the alleles  of the male are represented by XY” where X chromosome has no trait of long tails find  

And the allels of the female are represented by XX, as they do not have long tail fins.  

When these two are crossed , the following punnet square is produced

X     Y”

X X X    X Y”

X X X     X Y”

The XX is the female while the XY” is the male offspring.

A population of 100 tigers has 30 with horizontal stripes. Using pedigrees, you ascertain that horizontal striping is caused by
bixtya [17]

Assuming that this population is in Hardy-Weinberg equilibrium, we can sayt that  <em>the</em><em> probability</em><em> that, given enough time, all tigers in the population will have horizontal stripes is</em><em> 30% = 0.3.</em>

--------------------------

<u>Available data:</u>

  • Population size, N = 100 tigers
  • Number of Tigers with horizontal stripes = 30
  • Horizontal stripes is caused by an autosomal recessive mutation.

We need to know the probability that all tigers in the population will have horizontal stripes, which is the recessive phenotype.

We assume that the population is in Hardy-Weinberg equilibrium, so there should be no evolution.

Since the population is in H-W equilibrium, the allelic, genotypic and phenotypic frequencies will remain the same generation after generation.

Now, we will calculate the allelic and genotypic frequencies of horizontal striped individuals in the population.

There are 100 individuals, and only 30 have horizontal stripes.

So, the phenotypic frequency, F(HS) is 30/100 = 0.3 = 30%

Since this is a recessive phenotype, this value equals the genotypic frequency, F(hh) = 30%

Finally, we can get the allelic frequency by taking the square root of this value.

F(hh) = q² = 0.3

f(h) = q = √0.3 = 0.55 = 55%

According to these calcs, the probability for the fixation of the recessive allele is 55%, and the probability that all individuals express the recessive horizontal stripes phenotype is 30%.
