Crossing over contributes to genetic variation by exchanging chromosomal segments between non-sister chromatids of homologous chromosomes.
What is crossing over?
- Crossing over is the exchange and recombination of genetic components between the homologous chromosomes.
- This occurs in the pachytene stage of the meiosis-1 of the meiotic division.
- Crossing over occurs with the help of an enzyme and the enzyme responsible for crossing over is called Recombinase.
Thus, crossing over contributes to genetic variation by exchanging chromosomal segments between non-sister chromatids of the homologous chromosomes.

Answer:
corrugated cardboard tube - digestive tract
irregular surfaces on the corrugated tube - villi
pump - heart
Plastic tubing - blood vessels
Explanation:
The corrugated cardboard tube represents the digestive tract. The give away was the presence of the irregular surfaces within the tubes. This is called the villi. The villi is responsible for the absorption of food after digestion into the body.
Irregular surfaces on the corrugated tube represent the villi. They are tiny hair-like structures that are in the small intestine, that are responsible for the absorption of food into the bloodstream.
The pump represents the heart. The heart is the only organ in the body that provides the pressure force that pushes the blood throughout the body. In this model, the pump will most likely be performing the same function.
The plastic tubings are meant to contain one form of fluid or the other. Judging from that, they can be said to represent the blood vessels. This is because they are connected to the heart and are meant to transport bodily fluids around the body
