The answer is negative controls. These are groups where no phenomenon is probable. They ensure that there is no effect when there should be no effect. Where there are only two possible outcomes, e.g. positive or negative, if the treatment group and the negative control both produce a negative result, it can be concluded that the treatment had no effect. If the negative control group and the treatment group both yield a positive result, it can be inferred that a puzzling variable is involved in the occurrence under study, and the positive results are not only due to the treatment. In other examples, outcomes might be measured as lengths, times, percentages, and so forth.
The probability of obtaining a yellow-fruited plant from the cross is ¼ or 25%.
<h3>WHAT IS A HETEROZYGOUS CROSS</h3>
A heterozygous cross is a cross between two individuals that are heterozygous for two genes.
According to this question, white (W) fruit color is dominant over yellow (w). If two white-fruited individuals with genotypes that are unknown are crossed i.e. Ww × Ww.
The offsprings of this cross are as follows:
Therefore, the probability of obtaining a yellow-fruited plant from the cross is ¼ or 25%.
