Consider the data on cliff swallow mortality. Why is this an example of directional selection?Overall genetic variation decrease
Gala2k [10]

Answer:

The average trait value changed in one direction.(In this case, larger size)

Explanation:

In evolution a natural selection can be disruptive, directional or stabilizing

In stabilizing no extreme trait is favored hence provides intermediate values .

Disruptive selection both extreme traits are favored over the intermediate trait.

Directional, the enviroment will favor the survival of one trait hence a change in direction either towards the left or the right.

In the case of swallow cliff mortality, selection favored the larger size.

how many dna molecules would there be after four rounds of pcr if the initial reaction mixture contained two molecules?
Marat540 [252]
  1. Answer: 32 molecules of DNA would be after four PCR if the initial reaction mixture contained two molecules
  • After 'n' rounds of the polymerase chain reaction, it is feasible to produce 2 n DNA molecules from a single DNA template molecule (PCR). Therefore, 2 to the power 4  = 16 DNA molecules will be produced after 4 PCR cycles
  • If two molecules are doubled four times, 32 DNA molecules are created.

Explanation:

The PCR method is what?

The highly sensitive PCR method enables quick DNA amplification of a particular section. Using visual methods based on size and charge, PCR may detect and identify gene sequences by producing billions of copies of a certain DNA fragment or gene.

What does a PCR have to accomplish?

A given DNA segment can be quickly multiplied (amplified) into millions or billions of copies using the polymerase chain reaction (abbreviated PCR), allowing for more in-depth analysis.

What are the three main PCR steps?

For any DNA synthesis reaction, there are only three easy stages that must be completed: First, the template is denaturated into single strands. Next, primers are annealed to each original strand to synthesise new DNA strands. Finally, the new DNA strands are extended from the primers.
