Complete, Incomplete and Co-Dominance Inheritance Flashcard

Front

What is Complete Dominance?

Back

A type of inheritance where one allele completely masks the effect of another allele in a heterozygote.

Front

What is Incomplete Dominance?

Back

A type of inheritance where the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes.

Front

What is Co-Dominance?

Back

A type of inheritance where both alleles in a heterozygote are fully expressed, resulting in a phenotype that shows both traits.

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 specific gene.

Front

What does homozygous mean?

Back

Having two identical alleles for a specific gene.

Front

What is a Punnett square?

Back

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

Front

What is the phenotypic ratio?

Back

The ratio of different phenotypes that appear in the offspring from a genetic cross.

Front

What is the genotypic ratio?

Back

The ratio of different genotypes that appear in the offspring from a genetic cross.
