Expert Solution & Answer

Explanation of Solution

During any experiment, the placebo is used as a substance, which have 0 value of the experimental variable. The placebo helps in maintaining the similar condition for the experimental and the control group. This way, the placebo allows to minimize the effect of other variables, such as temperature, pressure, etc.

Conclusion

The placebo allows treatment of the control group similar to the experimental group except for the independent variable being tested in the experimental group. Hence, it reduces the effect of other variables, which are not required to be tested.

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible. Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
