Genetics--Patterns of Inheritance

Front

What is incomplete dominance?

Back

A genetic situation where one allele does not completely dominate another, resulting in a phenotype that is a blend of both alleles.

Front

What is codominance?

Back

A genetic situation where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that shows both traits.

Front

What is complete dominance?

Back

A genetic situation where one allele completely masks the effect of another allele in a heterozygote.

Front

What phenotype ratio is expected from a cross of two heterozygous parents in incomplete dominance?

Back

1:2:1

Front

How do codominance and incomplete dominance differ?

Back

In codominance, both alleles are fully expressed, while in incomplete dominance, the alleles blend.

Front

What type of dominance is shown by a flower with both red and white petals?

Back

Codominance

Front

What type of dominance occurs when one allele completely masks another?

Back

Complete dominance

Front

What is a Punnett square used for?

Back

A tool used to predict the genotypes and phenotypes of offspring from a genetic cross.

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, often represented by alleles.
