Question

the diagram shows two chromosomes paired up. which process is being shown? ○ sexual reproduction ○ independent assortment ○ crossing over ○ chromosome separation

Explanation:

The diagram shows chromosomes paired up with segments potentially exchanging, which is characteristic of crossing over (a process in meiosis where homologous chromosomes exchange genetic material). Sexual reproduction is a broader concept, independent assortment involves different chromosome pairs, and chromosome separation is about moving apart. So the process is crossing over.

Answer:

B. crossing over (assuming the option for crossing over is labeled as such; if the original options had labels like A, B, etc., adjust accordingly. From the text, the option "crossing over" is the correct one for the process of chromosome pairing with exchange - like behavior shown.)
