Question

the diagram shows a pair of homologous chromosomes before and after a process takes place. the change is most likely the result of which process? crossing - over disjunction hybridization segregation

Explanation:

Crossing - over is the exchange of genetic material between homologous chromosomes. In the diagram, we can see that genetic segments (represented by different alleles like W/w and Z/z) have been swapped between the homologous chromosomes. Disjunction is the separation of chromosomes during cell division, hybridization is the process of combining different genetic material from different species, and segregation is the separation of alleles during gamete formation. None of these other processes match the visual change shown in the diagram as well as crossing - over.

Answer:

A. crossing - over
