Answer:

<em><u>The answer is</u></em>: <u>a. Genetic drifts originate from the error, in this case: c. Bottleneck.</u>

Explanation:

Genetic drift, also known as allelic drift is an evolutionary force that acts together with natural selection by changing the allelic frequencies of species over time.

Bottleneck, is that a population undergoes a drastic reduction in its size, giving rise to a population with a high probability of suffering genetic drift. Any mutation in an individual will be amplified in the community when it grows again. Bottleneck events are also characterized by producing a reduction in the genetic diversity of species, due to the extinction of less frequent alleles.

<em><u>The answer is</u></em>: <u>a. Genetic drifts originate from the error, in this case: c. Bottleneck.</u>

prisoha [69]

To calculate the frequency of the heterozygote genotype (Pq) for this gene we must use the Hardy-Weinberg equation ( p2 + 2pq + q2 = 1 ). This equation relies on the Hardy-Weinberg principle, a model in population genetics that states that the frequency of the alleles in a population is never changing, only the combinations (the genotypes) are changing.

If there are only two alleles (variations) of this gene in a population, then their frequencies should add up to 1 (100%). From this, we can calculate the frequency of the q allele.

p +q=1

0,3 +q=1

q= 1-0,3

q= 0,7

Now hat we have the frequency of the q allele we can use the HW equation to calculate the frequency of the heterozygotes.

p^{2} + 2pq + q^{2} = 1

(0,3)^{2} + 2pq +(0.7)^{2} = 1

0,09 + 2pq +0.49= 1

2pq +0,58= 1

2pq= 1-0.58

2pq=0,42

The freqency of the heterozygotes in this population is 0.42

So you know that there are 3,000,000 of bacteria in one gram of soil so you multiply 3,000,000×10 and you get 30,000,000. Then you just check all your options. So it's 3×10^7.

Igoryamba

Answer:

The blank is "apart."

Explanation:

Mid-ocean ridges are geologically important because they occur along the kind of plate boundary where a new ocean floor is created as the plates spread apart. Thus the mid-ocean ridge is also known as a "spreading center" or a "divergent plate boundary." The plates spread apart at rates of 1 cm to 20 cm per year.
