A population of wild-flowers was scored for flower color. There were 302 blue (BB) plants, 1857 violet (BR) plants and 811 red (

RR) plants. Please round your answer correctly to 4 decimal digits.
(a) What is the frequency of the blue (B) allele?
(b) What is the frequency of the red (R) allele? Please round your answer correctly to 4 decimal digits.

A chi-square test was conducted to test the hypothesis that the population genotypic frequencies are consistent with Hardy-Weinberg equilibrium frequencies.
(c) What is the expected number of blue (BB) plants? Please round your answer correctly to 4 decimal digits.
(d) What is the expected number of violet (BR) plants? Please round your answer correctly to 4 decimal digits.
(e) What is the expected number of red(RR) plants? Please round your answer correctly to 4 decimal digits.

Answer:

frequency of the blue (B) allele = 0.4142

frequency of the red (R) allele = 0.5858

The number of blue plants expected is 509.652

The number of red plants expected is 1019.304

The anticipated number of violet plants is 1441.341

Calculated chi square value

= 84.5320 + 42.5688 + 119.8692\\= 246.97

Explanation:

Frequency of blue allele is

Frequency of blue allele is equal to sum of frequency of BB and half of frequency of BR

\frac{302}{2970} + \frac{1}{2} \frac{1857}{2970} \\= 0.1016 + 0.3126\\= 0.4142

Frequency of other allele

1- 0.4142\\= 0.5858

Chi Square test

See the attached file

The number of blue plants expected is 509.652

The number of red plants expected is 1019.304

The anticipated number of violet plants is 1441.341

Calculated chi square value

= 84.5320 + 42.5688 + 119.8692\\= 246.97

What happens when there is a high concentration of positive transcription factors but a low affinity for the positive transcript
Troyanec [42]

When there is a high concentration of positive transcription factors but a low affinity for the positive transcription factor

Transcription factors are proteins that regulate the transcription of genes—that is, their copying into RNA, on the way to making a protein.

Proteins called transcription factors, however, play a particularly central role in regulating transcription. These important proteins help determine which genes are active in each cell of your body.

<h3>How does transcription factors affect gene expression?</h3>

Under the influence of transcription factors, the various cells of the body can function differently though they have the same genome. Transcription factors attach to one or more series sites, which are called transcription element binding sites (TFBSs), binding to specific DNA sequences of the genes they control

How to explain natural selection?
loris [4]
Natural selection is basically when organisms with the best traits survive and pass on their good traits to their offspring so that they will adapt easily and survive. Organisms who do not have ‘good traits’ that help them adapt and escape predators will be killed or eaten before they reproduce.
So in the end, natural selection is a form of evolution that allows the ‘fittest’ animals to survive and reproduce, while weeding out the unfit.
