Explain two ways chromosomal mutations can occur during meiosis

There are many ways that chromosomal mutations can occur, but for starters:

Duplication: Happens when extra copies of a specific gene are generated on a chromosome.

Inversion: Inversion includes when a broken chromosome segment is reversed and sent back into the chromosome.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
