Answer:

A. double-blind

Explanation:

Based on the scenario being described within the question it can be said that the type of trial that she has joined is known as a double-blind study. This is a type of study in which individuals are chosen randomly for each clinical intervention and the results are not given to the researchers until after the trial. This also includes any and all information that may influence the researchers behavior or thoughts on the study.

Answer:

In Medicine, Double-blind study is a type of trial in which neither the patient nor the doctor running the trial will know until the process has been completed.

It is usually aimed at preventing bias in a scientific research or experiment to the placebo effect.

Round seeds are dominant over wrinkled seeds in
antoniya [11.8K]

Genotype - RR - 25%, Rr - 50%, rr - 25% (1:2:1)

Phenotype - Round seeds - 75%, Wrinkled seeds - 25% (3:1)

<h3>How explain your answer?</h3>

Let the letter "r" stand for the alleles, where R is round seeds and r is wrinkled seeds. A genotype is an individual's genes represented through alleles. Phenotypes are how the genes express themselves. In other words, genotypes will be written using letters, the alleles, and phenotypes will be the possible outcomes of the alleles.

Both of the parent seeds have the genotypes Rr and the phenotype of round seeds.

If you create punnet square (which had four boxes in total) 1 will have RR, 2 will have Rr, and 1 will have rr. These are the ratios for the genotypes. Each box represents 25%, so the percentages will be 25, 50, and 25. Finally, 3 of these boxes (RR and Rr) will result in round seeds because those are dominant. Only the genotype rr will result in wrinkled phenotype. Therefore, the ratio is 3:1 or 75% to 25%.

Thus, this could be the answer.
