Question

1. 7 points 32 in the early 1900s, thomas hunt morgan was among the first scientists to contribute to the chromosome theory of heredity. morgans investigations into heredity in fruit flies led him to propose that the event represented in the diagram sometimes occurs. which statement about the event represented in the diagram is valid? p the event represents rna translation in the smooth endoplasmic reticulum. g the event takes place in bacterial cells. h the event produces genetically identical daughter cells. j the event provides genetic diversity in eukaryotic cells. f g h j

Explanation:

The diagram represents crossing - over (homologous recombination) in eukaryotic cells.

• Option F: RNA translation occurs on ribosomes, not related to the diagram.
• Option G: Bacterial cells do not undergo meiosis (where crossing - over occurs in eukaryotes). Bacteria have different genetic recombination mechanisms like conjugation, transduction, and transformation.
• Option H: Crossing - over occurs during meiosis. Meiosis produces non - identical daughter cells (gametes). Mitosis produces genetically identical daughter cells.
• Option J: Crossing - over during meiosis exchanges genetic material between homologous chromosomes, which provides genetic diversity in eukaryotic cells.

Answer:

J. The event provides genetic diversity in eukaryotic cells.
