Question

multiple choice 1 point the diagram above illustrates which of the following processes? post transcriptional processing crossing - over deletion duplication base pair substitution

Explanation:

The diagram shows homologous chromosomes exchanging genetic material, a key feature of crossing - over (occurring during meiosis, specifically prophase I). Post - transcriptional processing involves RNA modification (not chromosome - level changes). Deletion removes genetic material, duplication repeats it, and base - pair substitution is a point mutation. None of these match the chromosome - segment exchange seen here.

Answer:

Crossing - over (the option labeled "Crossing - over")
