Plaque assays are often used to estimate the number of virions in a sample of a particular volume (the titer). The count is give

n as plaque-forming units. Which of the following is NOT generally a concern that must be considered in evaluating the results of plaque assays?
a.The plaques must be at a density that can be counted on the plate; high and low densities may result in inaccurate counts.
b.The plaques must be clearly visible in order to be counted accurately; this technique cannot be used with viruses that do not cause clear cellular damage.
c.The largest problem is that single viruses may create multiple plaques, resulting in overestimates of the number of viruses present.
d.The largest problem is that the count may underestimate the total number of viral particles, as not all virions may be able to cause infection.

Answer:

c) The largest problem is that single viruses may create multiple plaques, resulting in overestimates of the number of viruses present.

Explanation:

  • Plaque-based assays are the accepted method used for finding virus concentration in terms of infectious dose.
  • Viral plaque assays determine the number of plaque forming units (pfu) in a virus sample, which is one measure of virus quantity.

The graph below is of directional selection. Which statement can be supported by the evidence shown in the graph?
7nadin3 [17]

<u>Answer</u>: C) Directional selection occurs when one of two extreme phenotypes is selected for.

The type of natural selection known as directional selection is defined in population genetics in the case in which an extreme phenotype is favored over other phenotype. Thus, the population and its allele frequency will evolve towards this end of the trait spectrum (extreme phenotype). This is also the case illustrated in the graph where the right side represents the extreme phenotype.

If a pink snapdragon is self-fertilized, the offspring are red, pink, or white. What type of inheritance pattern does flower col
BaLLatris [955]

The type of inheritance pattern flower color exhibited in this example is incomplete domination (Intermediate).

<h3>What is meant by incomplete dominance?</h3>

Incomplete dominance or partial dominance is gene expression in offspring based on phenotypic observations that mediate from crosses of parents with different and contrasting characters.

Why intermediate traits can appear in an individual?

An intermediate trait occurs when both heirs are equally strong. The two inheritors of nature are neither closed nor covered. On the other hand, the parents will cover each other because they are just as strong. Offspring with intermediate traits will carry the same combination of traits from both parents.
