The Hardy-Weinberg Principle
1. What is allele frequency?
2. What is genetic
equilibrium?
3. What is the mathematical
expression of the genetic
equilibrium for genes with two
alleles? Is this statistical
distribution the same as the
statistical distribution of the
respective phenotypes?
4. An hypothesis for the
extinction of the dinosaurs is
that the earth had been hit by
a gigantic meteor that caused
the death of those big reptiles.
In that case the entire genetic
pool of those animals has
been destroyed, invalidating
the Hardy-Weinberg
equilibrium. In Genetics what
is this type of gene frequency
change called?
5. What are thepenetrance
and theexpressivityof a
gene?
6. Why is a balanced
frequency of different alleles
of a gene in a population more
useful for the survival of that
population facing
environmental changes?
