Question

In the ancestral lineage leading to land plants, a gene duplication in the developmental gene OEP16 is known to have been followed by the process of neofunctionalization. Which of the following statements is FALSE regarding these genes?

a. The genes produced by neofunctionalization are OEP16L and OEP16S.

b. The two genes produced by duplication are very similar in how they are expressed within a plant.

c. The neofunctionalization of the OEP16 gene may have been partly responsible for the explosion of plant diversity and the evolution of flowering land plants.

d. The duplication in the OEP16 gene took place in the lineage that led to the land plants.

Explanation / Answer

Answer - b. The two genes produced by duplication are very similar in how they are expressed within a plant.

Reason

OEP16L is expressed in leaves and its expression is sensitive to temperature change.

OEP16S is expressed during maturation period of seeds and pollen grain.
