Mendelian and Nonmendelian Genetics Practice

Front

What is a gene?

Back

A segment of DNA that codes for a particular protein, leading to a specific trait.

Front

What type of inheritance occurs when two alleles blend together?

Back

Incomplete Dominance.

Front

What is codominance?

Back

When one allele is not dominant over the other, resulting in both traits being expressed in a heterozygous individual.

Front

What does a Punnett square represent?

Back

A diagram used to predict the outcome of a genetic cross.

Front

What is the difference between homozygous and heterozygous genotypes?

Back

Homozygous has two identical alleles, while heterozygous has two different alleles.

Front

What is an allele?

Back

A variant form of a gene.

Front

What is Mendelian inheritance?

Back

A type of inheritance that follows the laws established by Gregor Mendel, primarily involving complete dominance.

Front

What is polygenic inheritance?

Back

Inheritance of traits that are controlled by multiple genes.
