What is Monohybrid Inheritance?

Back

A type of inheritance that involves a single pair of contrasting traits, where one trait is dominant over the other.

What does the term 'allele' mean?

Back

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

What is the difference between dominant and recessive alleles?

Back

A dominant allele is expressed in the phenotype even if only one copy is present, while a recessive allele is only expressed when two copies are present.

Front

Define Homozygous.

Back

When an individual has two identical alleles for a particular gene.

Front

Define Heterozygous.

Back

When an individual has two different alleles for a particular gene.

Front

What is a genotype?

Back

The genetic makeup of an individual, represented by the alleles they possess.

Front

What is a phenotype?

Back

The observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What does it mean for an allele to be dominant?

Back

A dominant allele is one that will express its trait in the phenotype even if only one copy is present.

Front

What does it mean for an allele to be recessive?

Back

A recessive allele will only express its trait in the phenotype if two copies are present, with no dominant allele.

What is a Punnett square?

Back

A diagram used to predict the outcome of a genetic cross by showing the possible combinations of alleles from the parents.
