<span> I would have to say that Homologous chromosomes are made up of chromosome pairs of approximately the same length, centromere position, and staining pattern, for genes with the same corresponding loci that's all I know</span>

The distribuition of alleles changes due to random chance.
Answer:
higher-order conditioning
Explanation:
Pavlov found that a conditioned stimulus with a neutral (unconditioned stimulus ) associated, the dogs will experience the same previous salivation. First food was provided at the same time a bell ring, then the removal of the food, which was a natural trigger to making the dogs salivate was not present, still when ringing the bell, the dogs would act as if they were in front of the food.
This also called Higher Order Conditioning was the cornerstone of Pavlov findings.

Answer:
The correct answer is A. stabilizing selection
Explanation:
Stabilizing selection is one type of natural selection that occurs when the population having non-extreme traits are stabilized. It results in overexpression of a particular trait in a population. Here most average individual gets selected.
So as the stabilizing selection favors the middle phenotype and not extreme phenotypes it decrease the genetic variation. So here individuals who are having extremely long snout are selected therefore a particular trait is selected and overexpressed in the population. So it is an example of stabilizing selection.
