Textbook Question
Chapter 27, Problem 5EQ
You will need to refer to question 2 in More Genetic TIPS before answering this question. In an island population, the following data were obtained for the numbers of people with each of the four blood types:
Type O 721
Type A 932
Type B 235
Type AB 112
Is this population in Hardy-Weinberg equilibrium? Explain your answer.

A population consists of 300 individuals with the following genotypes:
AA – 100 Aa – 125 aa – 75
a. What are the values of p and q?
b. Is the population in Hardy-Weinberg equilibrium? Explain.
A population consists of 20% AA, 30% Aa and 50% aa. What is the frequency of the A allele in this population?
Give typing answer with explanation and conclusion
If 80% of a population has a heterozygous phenotype, and 16% of that population shows arecessive phenotype, is that population in Hardy-Weinberg equilibrium? In other words, doesthe population obey the rules of H-W? Perform a statistical analysis to determine your finalanswer.
