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

an autosomal recessive mutation. What is the probability that, given enough time, all tigers in the population will have horizontal stripes

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%.

Check all the functions that take place within the eukaryotic cytoplasm.
sesenic [268]

The cytoplasm is a fluid substance that fills every living cell which is enclosed by the cell membrane. This substance is mainly composed of water and proteins.

The functions that take place within the eukaryotic cytoplasm are diverse:

  • Location for most metabolic pathways. Except for the metabolic pahtways in cell nucleus and cytoplasmatic organelles, all metabolic functions (e.g., synthesis of biomolecules, growth, etc) occur in the cytoplasm.  The cytoplasm contain enzymes (i.e., proteins) to carry out different chemical reactions.

  • Location for organelles that house many of the metabolic pathways for the cell. For example, the synthesis of ATP (the energy coin of the cells) is carried out in the mitochondria, which are organelles found in the cytoplasm.

  • Location for the cytoskeleton that gives integrity to the cell. The cytoplasm contains all of the three types of filaments of the cytoskeleton (i.e., microtubules, actin filaments, and intermediate filaments) which provides structural support to the cells.

On the other hand, in plant cells, the cell wall is located outside the cell membrane.
