Final answer:
Crossover events are the recombination events that alter the arrangement of genes within the genome.
Step-by-step explanation:
The name of recombination events that alter the arrangement of genes within the genome is crossover events. During meiosis, a single crossover event between homologous non-sister chromatids leads to a reciprocal exchange of equivalent DNA between a maternal chromosome and a paternal chromosome. This results in a combination of maternal and paternal genes that did not exist before the crossover, creating genetic variation.
