Patterns of Inheritance

Front

What is Codominance?

Back

A pattern of inheritance where both alleles in a heterozygous individual contribute equally and visibly to the phenotype.

Front

What is Incomplete Dominance?

Back

A pattern of inheritance where the phenotype of a heterozygous individual is intermediate between the phenotypes of the two homozygous parents.

Front

What is Complete Dominance?

Back

A pattern of inheritance where the dominant allele completely masks the effect of the recessive allele in a heterozygous individual.

Example of Codominance in animals?

Back

A calico cat showing both orange and black fur.

Front

Example of Incomplete Dominance in plants?

Back

A red flower crossed with a white flower producing pink flowers.

Front

What is a phenotype?

Back

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

Front

What is a genotype?

Back

The genetic constitution of an individual, specifically the alleles present at a given locus.

Front

What does heterozygous mean?

Back

Having two different alleles for a particular gene.

Front

What does homozygous mean?

Back

Having two identical alleles for a particular gene.

Front

What is the principle of independent assortment?

Back

The principle stating that alleles for different traits are distributed to gametes independently of one another.
