Answer:

B. It allows for genetic variation.

As prophase progresses, homologous chromosomes come to lie side by side and become intertwined rather like a zipper. This process is called synapsis. During synapsis, homologous chromosomes exchange genetic material between one another which allows for genetic variation. This exchange is called crossing over.

The environment will not be able to sustain the cows anymore until the herd number reduce.
