Front

What is heredity?

Back

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

Front

What is a dominant trait?

Back

A dominant trait is a characteristic that is expressed when at least one dominant allele is present in the genotype.

Front

What is a recessive trait?

Back

A recessive trait is a characteristic that is expressed only when two recessive alleles are present in the genotype.

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, represented by the alleles it possesses.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype.

Front

What does homozygous mean?

Back

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

Front

What does heterozygous mean?

Back

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

Front

What are alleles?

Back

Alleles are different forms of a gene that can exist at a specific locus on a chromosome.

Front

How many alleles does an organism have for each trait?

Back

An organism has two alleles for each trait, one inherited from each parent.

Front

What is the significance of a Punnett square?

Back

A Punnett square is a diagram used to predict the genetic outcomes of a cross between two organisms.
