Non-Mendelian Genetics

Front

What is the term for traits controlled by multiple genes, such as height and skin color?

Back

Polygenic traits

Front

What type of inheritance occurs when both traits are fully expressed in the phenotype?

Back

Codominance

Front

In a Punnett square, what does each box represent?

Back

Potential offspring

Front

What term describes a phenotype that can be influenced by environmental factors?

Back

Plastic

Front

What is the non-Mendelian inheritance pattern where neither trait is dominant and traits blend together?

Back

Incomplete dominance

Front

What is the difference between Mendelian and non-Mendelian inheritance?

Back

Mendelian inheritance follows simple dominant and recessive patterns, while non-Mendelian inheritance includes patterns like codominance, incomplete dominance, and polygenic traits.

Front

What is an example of a polygenic trait in humans?

Back

Height or skin color

Front

How does codominance differ from incomplete dominance?

Back

In codominance, both traits are fully expressed, while in incomplete dominance, the traits blend to form a new phenotype.

Front

What is the significance of a Punnett square in genetics?

Back

It is used to predict the genotypes and phenotypes of potential offspring from parental crosses.

Front

What does it mean for a trait to be influenced by both genetics and the environment?

Back

It means that the phenotype can change based on environmental conditions, indicating plasticity.
