What is an example of an increase in the number of heterozygous individuals in the population due to conferred protection from a trait, such as in sickle-cell anemia and malaria immunity?

Domain, Phylum, Class, Family
Incomplete Dominance
Monera
Selective pressure

The correct answer is: Selective pressure

An increase in the number of heterozygous individuals in the population due to conferred protection from a trait is a result of selective pressure. Incomplete dominance is a genetic inheritance pattern where one allele is not completely dominant over another, rather than conferred protection from a trait. Domain, Phylum, Class, and Family are all taxonomic categories, not examples of an increase in the number of heterozygous individuals. Monera is an outdated biological kingdom that was once used to classify certain types of bacteria, and is not related to conferred protection or heterozygosity in a population.
