Front

What is a dihybrid cross?

Back

A dihybrid cross is a genetic cross that examines the inheritance of two different traits, each controlled by different genes.

Front

What does the term 'genotype' refer to?

Back

Genotype refers to the genetic makeup of an organism, specifically the alleles it possesses for a particular trait.

Front

What does the term 'phenotype' refer to?

Back

Phenotype refers to the observable characteristics or traits of an organism, which result from the interaction of its genotype with the environment.

Front

What is the purpose of using the F.O.I.L method in genetics?

Back

The F.O.I.L method is used to determine the possible allele combinations from two parent genotypes in a dihybrid cross.

Front

What are alleles?

Back

Alleles are different versions of a gene that determine specific traits in an organism.

Front

What is the significance of the Punnett square in genetics?

Back

A Punnett square is a tool used to predict the genotypes and phenotypes of offspring from a genetic cross.

Front

What does 'homozygous' mean?

Back

Homozygous refers to having two identical alleles for a particular gene (e.g., AA or aa).

Front

What does 'heterozygous' mean?

Back

Heterozygous refers to having two different alleles for a particular gene (e.g., Aa).

Front

What is the expected phenotypic ratio in a dihybrid cross?

Back

The expected phenotypic ratio in a dihybrid cross is typically 9:3:3:1.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their trait even when only one copy is present, while recessive alleles require two copies to express their trait.
