A punnet square can be described as a diagram which is made to predict the genotype as well as the phenotypes of the offsprings of a cross.
To study the epistatis nature of the pigmentation in bear, a punnet square was made and the results of the punnet square are shown above.
The results of the punnet square show that the cross between two bears will have the chances of producing 9/16 black bears, 3/16 brown bears and 4/16 white bears.

The chief difference between arteries<span> and </span>veins<span> is the job that they do. </span>Arteries<span> carry oxygenated blood away from the heart to the body, and </span>veins<span> carry oxygen-poor blood back from the body to the heart.
Another difference would be v</span><span>eins have valves and arteries do not. In arteries, blood flows in the right direction because of the heart pumping it forwards at high pressures. The lower blood pressure in veins means that valves are needed to stop blood flowing backwards (for example, in veins in the legs, blood needs to flow upwards against the pull of gravity).</span>
If I understand you correctly; the two experimental treatments are the experimental condition and the control condition.
The thing differing between them should be what you want to examine, and especially the thing you want to know of how it influences something. So for example if you want to know how alcohol influences something, the difference should be that one condition will include alcohol and the other won't.
