Question

independent assortment is a process where the alignment of homologous chromosomes during meiosis i is random. this process contributes to genetic variation, as gamete formation results in unique combinations of genetics. which diagram best shows crossing - over? a diagram of a circle with some segments and arrows b diagram of a wavy line with some small figures near it

Explanation:

Step1: Recall crossing-over definition

Crossing-over is the exchange of genetic material between homologous chromosomes during meiosis, visible as overlapping segments with allele exchange.

Step2: Analyze diagrams

Diagram A shows a circular structure (likely independent assortment), while Diagram B shows homologous chromosomes with overlapping segments and allele exchange (key feature of crossing-over).

Answer:

B. [Diagram B showing overlapping chromosomes with allele exchange]
