ABO blood type is examined in a Taiwanese population, and allele frequencies are determined. In the population, f(Iᴬ)=0.30, f(Iᴮ)=0.15, and f(i)=0.55.f. Assuming Hardy–Weinberg conditions apply, what are the frequencies of genotypes, and what are the blood group frequencies in this population?

Key Concepts

Hardy-Weinberg Principle

The Hardy-Weinberg Principle states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of evolutionary influences. This principle provides a mathematical framework to predict the expected frequencies of genotypes based on allele frequencies, assuming no mutation, migration, selection, or genetic drift.

Allele Frequency

Allele frequency refers to how often a particular allele appears in a population compared to other alleles for the same gene. In the context of the ABO blood type, the frequencies of alleles Iᴬ, Iᴮ, and i are given, which are essential for calculating the expected genotype frequencies under Hardy-Weinberg conditions.

Genotype Frequency

Genotype frequency is the proportion of a specific genotype among all individuals in a population. For the ABO blood types, the genotype frequencies can be calculated using the allele frequencies and the Hardy-Weinberg equations, which help determine the expected distribution of blood types in the population based on the given allele frequencies.
