When a person has linked a neutral stimulus and an unconditioned stimulus so that now the neutral stimulus triggers the conditioned response, <u>acquisition</u> has occurred.
<u>Explanation:</u>
A trigger that in the beginning causes no specific answer other than attention concentration is understood as "a neutral stimulus". In operant conditioning the neutral stimulus becomes a conditioned stimulus when used in combined way with an unconditioned stimulus.
Now let us say, for instance, you need to take your child to the pediatrician for a shot. The pediatrist hits a buzzer before the shot to call her nurse to come in and help her conduct the vaccine. Here the buzzer's noise is the neutral stimulus, as it generates no reaction from the infant, but the child knows that.

Answer:
Genes lying close to each other on chromosome
Explanation:
When genes lie close to each other on chromosome, they are inherited together as an intact unit in meiosis cell division and such genes are termed as linked genes.During meiosis the genetic material (allele/genes) is exchanged between the homologous parent chromosome which causes chromosome recombination and thus the formation of linkages These genes have high chances of recombination as they lie close to each other.
