Biology
1 answer:

Answer:

B. It allows for genetic variation.

Explanation:

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.

Alenkinab [10]

<u>Answer</u>: Hybridization.

Hybridization is the process through which two species can mate with each other and produce fertile offspring thus creating a new species.

This is not happening with the two palm species on the island. This may be due to prezygotic barriers that prevent these two species from mating and producing a zygote (fertilized egg cell). In essence these barriers prevent any gene flow between the two species.
