Front

What is a homozygous gene?

Back

A homozygous gene is a gene that has two identical alleles, meaning it can only produce one type of protein.

Front

What is a trait?

Back

A trait is a characteristic or feature of an organism that is inherited from its parents.

Front

What is a feature of a species?

Back

A feature is a distinguishing characteristic that all members of a species share.

Front

What is a heterozygous gene?

Back

A heterozygous gene has two different alleles, which can produce two different proteins.

Front

What is a gene mutation?

Back

A gene mutation is a change in the DNA sequence that can lead to new traits, random changes, or new proteins being made.

Front

What is the difference between a gene and a trait?

Back

A gene is a segment of DNA that codes for a protein, while a trait is the observable characteristic that results from the expression of that gene.

Front

What are alleles?

Back

Alleles are different versions of a gene that can exist at a specific locus on a chromosome.

Front

What is the role of proteins in an organism?

Back

Proteins perform a variety of functions in the body, including building tissues, facilitating biochemical reactions, and supporting immune function.

Front

What does it mean for a gene to be mutated?

Back

A mutated gene has undergone a change that can alter the function of the protein it encodes.

Front

What is the significance of genetic variation?

Back

Genetic variation is important for the survival of a species as it allows for adaptation to changing environments.
