According to Figure 21.10b and its accompanying text, what are pseudogenes ψ ?
A: They are genes that are only expressed in the embryonic stage of development.
B: They are noncoding DNA regions that separate functional genes within a gene family.
C: They are versions of functional genes that no longer encode functional polypeptides.
D: They are genes that encode proteins with entirely different functions compared to their related functional genes.
Explanation
The text in Figure 21.10b's legend explicitly states: 'The noncoding DNA light blue separating the functional genes within each family includes pseudogenes ψ; gold , versions of the functional genes that no longer encode functional polypeptides.'
