Heredity

Front

What is heredity?

Back

Heredity is the passing of traits from parents to offspring through genes.

Front

What is a dominant allele?

Back

A dominant allele is an allele that expresses its trait even when only one copy is present in the genotype.

Front

What is a recessive allele?

Back

A recessive allele is an allele that only expresses its trait when two copies are present in the genotype.

Front

What does genotype refer to?

Back

Genotype refers to the genetic makeup of an organism, specifically the alleles it carries.

Front

What does phenotype refer to?

Back

Phenotype refers to the observable characteristics or traits of an organism, influenced by its genotype.

Front

What is a Punnett Square?

Back

A Punnett Square is a diagram used to predict the outcome of a genetic cross by showing the possible combinations of alleles.

Front

What is the genotype of a homozygous organism?

Back

A homozygous organism has two identical alleles for a particular trait (e.g., RR or rr).

Front

What is the genotype of a heterozygous organism?

Back

A heterozygous organism has two different alleles for a particular trait (e.g., Rr).

Front

In a genetic cross, what does the term 'F1 generation' refer to?

Back

The F1 generation refers to the first generation of offspring resulting from a cross between two parental organisms.

Front

What is the expected phenotype ratio in a monohybrid cross?

Back

The expected phenotype ratio in a monohybrid cross is typically 3:1 for dominant to recessive traits.
