At what level does gene variability quantify genetic variation?
sergejj [24]

Answer:

Answer is whole-gene or whole-genome.

Explanation:

Genetic variation explains that, no matter how related or identical some organisms might be, there is a or some characters that make them different from one another. These difference is referred to as variation.

Furthermore, whole-gene means the coding and non-coding regions of the DNA>

There are some activities or occurrences that cause genetic variation, these are gene flow, mutation and sexual reproduction.

Examples of genetic variation are color of the eyes, modification of leaf and blood type among others.

When pink sweet peas were self-pollinated and the seeds were collected and sown, the following flower colors were obtained: Red
Pavlova-9 [17]

Answer:

c. 1:2:1

The results are consistent with incomplete dominance for this trait, with pink flowers being heterozygous.

Explanation:

If flower color were determined by a gene showing incomplete dominance, the possible genotypes and phenotypes are as follows:

  • RR- red
  • ww - white
  • Rw - pink

If pink sweet peas are self-pollinated, then a cross between two heterozygous individuals is done (Rw x Rw).

<u>From this cross the expected ratios are:</u>

  • 1/4 RR (red)
  • 2/4 Rw (pink)
  • 1/4 ww (white)

So the null hypothesis is that the observed results exhibit a 1:2:1 ratio.

<h3><u>Chi square test</u></h3>

X^{2} = \sum \frac{(Observed - Expected)^2}{Expected}

<u>The observed frequencies were:</u>

  • 34 Red
  • 76 Pink
  • 40 White

Total 150

<u>The expected frequencies for our null hypothesis are:</u>

  • 1/4 x 150 = 37.5 Red
  • 2/4 x 150 = 75 Pink
  • 1/4 x 150 = 37.5 white

X^{2} = \frac{(34- 37.5)^2}{37.5} + \frac{(76- 75)^2}{75} + \frac{(40- 37.5)^2}{37.5}

X^2=0.5067

The degrees of freedom (DF) are calculated as number of phenotypes - 1; in this case DF = 3-1 = 2.

If we look at the Chi square table, for 2 DF and a probability of p0.05, the critical value is 5.991

Our X^2 value of 0.5067 is less than the critical value, so we do not reject the null hypothesis. The results are consistent with incomplete dominance for this trait, with pink flowers being heterozygous.

A researcher would like to determine the effect of caffeine on memory. Participants are randomly assigned to receive a caffeine
zhuklara [117]

Answer:

The placebo effect

Explanation:

The placebo effect in psychology refers to a situation in which participants in a research receive beneficial effects due to the administration of an inactive substance or a sham treatment. The positive beneficial effect received can then be attributed purely to believe and not to the treatment itself. A placebo treatment could produce a real healing effect like a true medical or psychological treatment.

The participants who received the sugar believed it to be a memory enhancing treatment hence the slight increase in memory capacity due to placebo effect.
