Answer:

B) genetic variation within chromosomes has increased

Step-by-step explanation:

Based on the diagram displayed in the image, a phenomenon called CROSSING-OVER or RECOMBINATION, unique in only meiotic division has occurred. Crossing-over occurs when chromosomal segment are exchanged between two non-sister chromatids of homologous chromosomes. As seen in the image, the chromosome segment containing B and b alleles were exchanged between non-sister chromatids of homologous chromosomes.

Crossing-over only occurs during meiosis or gamete formation and it increases the genetic variation among the species undergoing the process. It allows alleles in gametes to be recombined in a way that is different from the parental arrangement producing them. For example, in the image, a new recombination of Ab and aB has been formed instead of the parental AB and ab.
