Define the Hardy-Weinberg principle and discuss its importance Flashcards
What is the 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.
True or False: The Hardy-Weinberg principle assumes that evolution is occurring.
False
List the five conditions required for a population to be in Hardy-Weinberg equilibrium.
- No mutations 2. No gene flow 3. Random mating 4. Large population size 5. No natural selection
Fill in the blank: The Hardy-Weinberg equation is represented as _____ = p² + 2pq + q².
p + q
What do the symbols ‘p’ and ‘q’ represent in the Hardy-Weinberg equation?
‘p’ represents the frequency of the dominant allele, and ‘q’ represents the frequency of the recessive allele.
Multiple Choice: Which of the following is NOT a condition of the Hardy-Weinberg principle? A) Small population size B) No mutations C) Random mating D) No natural selection
A) Small population size
Short Answer: Why is the Hardy-Weinberg principle important in population genetics?
It provides a baseline to compare real populations against, helping to identify evolutionary changes.
True or False: The Hardy-Weinberg principle can be used to predict the genetic variation in a population over time.
True
What happens to allele frequencies in a population that is not in Hardy-Weinberg equilibrium?
Allele frequencies will change over time due to factors like selection, mutation, migration, or genetic drift.
Fill in the blank: The Hardy-Weinberg principle is a fundamental concept in _____ genetics.
