Answer:
The F2 generation can be explained because the alleles for flower colour and pollen shape are linked.
Explanation:
<em>When two alleles are linked on the same chromosome, there is a high tendency for the alleles to be inherited together. Consequently, the frequency of the alleles recombining in subsequent generations is low.</em>
This is what Bateson and Punnet observed. There exist a linkage between P and L alleles and also p and l alleles, thereby increasing their frequencies of occurring together and decreasing the frequency of their recombination.
Thus, the F2 generation observed by Bateson and Punnet is due to linkage of alleles.
The correct option is B.
Communication between cells can be inter communication or intra communication. Inter communication refers to a type of communication in which message is transfer from a near or distant cell to another cell, while the intra communication form of message transfer is one in which a message is been passed across within a single cell.
In the option B above, a single cell is involved and that is an example of an intra communication. The other options are example of inter communication.
Answer;
Forward chaining and backward chaining are Similar in that;
Both are used to teach a chain of behaviors.
Both use procedures,
Both teach one behavior at a time and chain the behaviors together.
Both procedures use prompting and fading to teach each component
Explanation;
-Backward chaining; When you teach the last stimulus-response component first. Then teach the next to last component and so on.
-Forward chaining; Teach the first stimulus-response component first. Then teach the second component and so on
