<span>Just as you've laid it out in your question. There is 1 YY (the only seed that will breed true for Yellow). There are 2 Yy, which are Y, but will not breed true for yellow, and there's 1 yy (which I'm guessing is green, and will only breed true for that color. Since that seed won't be included in with the seeds that are yellow, there are only 3 to choose from. </span>

<span>So that's a total of 3 yellow seeds, and out of those 3, only one is YY (true breeding for yellow) Your chance of picking up one seed and having it be YY (true breeding for yellow) is 1 in 3, or 33.3%</span>

5 goals of psychology?
Svetllana [295]
1. Describe - the first goal is to observe behavior and describe.
2. Explain - While descriptions come from observable data, psychologists must go beyond what is obvious and explain their observations. In other words, why did the subject do what he or she did?
3. Predict - Once we know what happens, and why it happens, we can begin to speculate what will happen in the future.
4. Control - Once we know what happens, why it happens and what is likely to happen in the future, we can excerpt control over it
5. Improve - Not only do psychologists attempt to control behavior, they want to do so in a positive manner, they want to improve a person’s life, not make it worse.

"what advantage do organisms that reproduce sexually have over organisms that reproduce asexually?"
makvit [3.9K]
Organisms that reproduce sexually have greater genetic and thus characteristic variations, and so, are able to withstand more selection pressures if they so happen to change or become greater. This increases the chances of survival for that species itself.

Organisms that reproduce asexually are genetically identical to each other. They are unlikely to withstand any changes in selection pressures.

Hope this helps! :)
