Question

Which statement describes the relationship between a gene's survival value and its genetic dominance?

Options

• Recessive genes with survival value are always lost from populations.

• Survival value is independent of dominance.

• Genes valuable for survival automatically become genetically dominant.

• Only dominant genes can confer a survival advantage.

Answer 1

The misconception is that genes valuable for survival automatically become genetically dominant. In reality, survival value is independent of dominance; valuable genes become more frequent whether they are genetically dominant or recessive.
