Question

In the early 1900s, Thomas Hunt Morgan was among the first scientists to contribute to the chromosome theory of heredity. Morgan’s investigations into heredity in fruit flies led him to propose that the event represented in the diagram sometimes occurs.

Which statement about the event presented in the diagram sometimes
occur?
A. The event represents DNA translation in the smooth endoplasmic
reticulum.
B. The event takes place in the bacterial cell.
C. The event produces genetically identical daughter cells.
D. The event provides genetic diversity in eukaryotic cells.

Answer 1

The correct answer is D

Answer 2

The statement about the event presented in the diagram sometimes occurs - D. The event provides genetic diversity in eukaryotic cells.

The given event in the diagram is known as crossing over which takes place during the process of meiosis.

• Crossing over takes place during the pachytene stage of Prophase I of Meiosis I where the non-sister chromatids of homologous chromosomes exchange genetic material
• this results in the recombination of the genetic material and creates a new genetic combination.
• Thus, genetic variations occur which can be beneficial to the offspring.

Thus, the statement about the event presented in the diagram sometimes occurs - D. The event provides genetic diversity in the eukaryotic cell.
