Back

AA

Front

What is the definition of mutation?

Back

A change in the DNA sequence that can lead to new traits.

Front

What is incomplete dominance?

Back

A genetic situation where one allele does not completely dominate another allele, resulting in a new phenotype.

Front

What is codominance?

Back

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 a genotype?

Back

The genetic constitution of an individual, represented by alleles.

Front

What is a phenotype?

Back

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