<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>

Kipish [7]

Option A, Acquisition

Explanation:

The first stage of learning is known as acquisition. It causes establishment of responses by pairing of Neutral stimulus, conditioning and un-conditioning stimulus. Once the association between a neutral stimulus and conditioned stimulus is established, the responses are acquired.  

For example – If a bird is trained to pick a key whenever there is a  sound of a bell, then after certain period of time an association will be established between the “ringing of bell” and “picking up of key” activity. Therefore, whenever the bird will hear the ringing sound it will search for key to be picked.

Thus, option A is correct.
