Front

In the Hardy-Weinberg Equation, what does q² represent?

Back

The frequency of the recessive genotype.

Front

How do you calculate the frequency of the genotype (bb) in a population with allele frequencies of 0.3 (B) and 0.7 (b)?

Back

Use the Hardy-Weinberg equation: q² = (0.7)² = 0.49.

Front

What type of carbohydrate is characterized by long chains of sugar molecules?

Back

Polysaccharide.

Front

What is a defining characteristic of prokaryotic cells?

Back

They have a single circular chromosome.

Front

If pressure potential = 0.2 MPa and solute potential = -0.6 MPa, what is the water potential?

Back

Water Potential = -0.4 MPa.

Front

What is the Hardy-Weinberg principle used for?

Back

To predict allele and genotype frequencies in a population that is not evolving.

Front

Define allele frequency.

Back

The proportion of a specific allele among all allele copies in a population.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup, while phenotype refers to the observable traits.

Front

What is a disaccharide?

Back

A carbohydrate formed by the combination of two monosaccharides.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis.
