<span>Proliferation of lymphocytes occurs immediately after activation, as well as the encounter of antigen. First, these antigen are bound, after which activation begins. Activation immediately leads to proliferation, as well as differentiation. Proliferation is an increase in the number of something, in this case, in the number of lymphocytes, or white blood cells. </span>
Answer:
<h2>L-A-D</h2>
Explanation:
Given:
In crossing over percentage equals to map unit, so 22 % equals to 22 map unit.
A and L are 6 map unit are closest one.
L and D are farthest away and have 27 map unit distance.
A-D =22 map unit
A-L = 5 map unit
L-d = 27 map unit
so the sequence of genes is L-A-D
In tropical regions basically warm and wet areas
