Definitions:

MN Blood Type

A blood group system classifying human blood based on the presence or absence of the M and N antigens on the surface of red blood cells.

Genotype Frequency

The proportion of a particular genotype in the population. Compare with allele frequency and phenotype frequency.

Aa Genotypes

Refers to the genetic makeup of an organism having one dominant allele (A) and one recessive allele (a) for a particular trait.

Hardy-Weinberg Predictions

Hardy-Weinberg predictions are mathematical expressions that describe the expected frequencies of genotypes in a population under certain conditions, including random mating and absence of evolutionary forces.
