Front

What are genes?

Back

Genes are segments of DNA that contain the instructions for building proteins, which determine the traits of an organism.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence of a gene, which can lead to changes in the traits of an organism.

Front

How do proteins influence traits?

Back

Proteins are responsible for the physical characteristics of an organism, as they perform various functions in the body and determine how traits are expressed.

Front

What is the relationship between genes and traits?

Back

Genes provide the instructions for making proteins, which in turn influence the traits of an organism.

Front

What does it mean for organisms to have different versions of a gene?

Back

Different versions of a gene, known as alleles, can lead to variations in traits among individuals.

Front

Why do offspring from different parents have different traits?

Back

Offspring inherit a combination of genes from both parents, leading to variations in traits.

Front

What is the significance of proteins connecting in different ways?

Back

Proteins connecting in different ways can result in different traits, as the structure and function of proteins are crucial for determining characteristics.

Front

What is the role of DNA in inheritance?

Back

DNA carries genetic information that is passed from parents to offspring, determining inherited traits.

Front

How can mutations affect an organism's survival?

Back

Mutations can lead to beneficial, harmful, or neutral changes in traits, affecting an organism's ability to survive and reproduce.

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 only expressed when two recessive alleles are present.
