Heredity

Front

What is heredity?

Back

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

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 definition of an allele?

Back

An allele is a variant form of a gene that can produce different traits.

Front

What is the difference between dominant and recessive alleles?

Back

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

Front

What is codominance?

Back

Codominance is a genetic scenario where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

Front

What is incomplete dominance?

Back

Incomplete dominance is when the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes.

Front

What is probability in genetics?

Back

Probability in genetics refers to the likelihood of a particular trait being passed on to offspring.

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 allele combinations.

Front

What is a genotype?

Back

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