Traits and Reproduction

Front

What is the main reason siblings and parents can be different from each other?

Back

Offspring inherit different combinations of gene versions from parents.

Front

How do gene versions influence traits in organisms?

Back

Each gene version provides a unique instruction to make a specific protein molecule in an organism's cells.

Front

What role do different protein structures play in determining traits?

Back

Different protein structures affect how they connect to other protein molecules.

Front

What does it mean for gene versions to be heterozygous?

Back

The two copies of a gene for each feature can be the different versions.

Front

What is a mutation in the context of genetics?

Back

A mutation is a change in an organism's genes.

Front

What is the definition of a gene?

Back

A gene is a segment of DNA that contains instructions for making a specific protein.

Front

What is the difference between dominant and recessive traits?

Back

Dominant traits are expressed when at least one dominant allele is present, while recessive traits are expressed only when two recessive alleles are present.

Front

How do environmental factors influence traits?

Back

Environmental factors can affect how genes are expressed, leading to variations in traits.

Front

What is the significance of genetic variation in a population?

Back

Genetic variation is important for the survival and adaptability of a species.

Front

What is the role of chromosomes in inheritance?

Back

Chromosomes carry genes and are passed from parents to offspring during reproduction.
