Genetic Variation in Populations

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA sequences among individuals within a population, which can lead to different traits.

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What causes differences in phenotype?

Back

Differences in phenotype are primarily caused by differences in genotype, which is the genetic constitution of an individual.

Front

What is a recessive phenotype?

Back

A recessive phenotype is the trait that is expressed only when an individual has two copies of the recessive allele.

Front

What does the genotype 'oo' represent?

Back

The genotype 'oo' represents a homozygous recessive condition for a trait.

Front

What is Hardy-Weinberg equilibrium?

Back

Hardy-Weinberg equilibrium is a principle that describes a population that is not evolving, where allele frequencies remain constant from generation to generation.

List the conditions for Hardy-Weinberg equilibrium.

1. No genetic mutations 2. Large population size 3. No natural selection 4. No migration (no new genetic material introduced)
