Mendelian & Non-Mendelian Genetics

Front

What is codominance?

Back

A genetic scenario where both alleles in a heterozygous individual contribute equally and visibly to the phenotype.

Front

What is incomplete dominance?

Back

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

Front

What is polygenic inheritance?

Back

A type of inheritance where multiple genes influence a trait, resulting in a continuous range of phenotypes.

Front

What is complete dominance?

Back

A genetic scenario where the dominant allele completely masks the effect of the recessive allele in a heterozygous individual.

Front

What is a genotype?

Back

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

Front

What is a phenotype?

Back

The physical expression or characteristics of a genotype, influenced by both genetic and environmental factors.

Front

What does homozygous mean?

Back

An individual with two identical alleles for a particular gene.

Front

What does heterozygous mean?

Back

An individual with two different alleles for a particular gene.

Front

What is a dominant allele?

Back

An allele that expresses its phenotype even in the presence of a recessive allele.

Front

What is a recessive allele?

Back

An allele that only expresses its phenotype when two copies are present (homozygous condition).
