Amplify T&R Flashcard Chapter 2

Front

What determines the physical traits of an organism?

Back

The physical traits of an organism are determined by proteins, which are influenced by the organism's genes.

Front

What is the difference between homozygous and heterozygous gene copies?

Back

Homozygous gene copies are identical (same alleles), while heterozygous gene copies are different (different alleles).

Front

How do proteins affect physical characteristics?

Back

Proteins affect physical characteristics by determining how traits are expressed, based on the genetic information they carry.

Front

What is the significance of having different parents in terms of physical traits?

Back

Having different parents can lead to variations in physical traits due to the combination of different genes and proteins.

Front

Can two organisms with the same proteins have different physical traits?

Back

No, if two organisms have the same proteins for a specific trait, they will likely have the same physical trait.

Front

What is an example of a trait that can vary among organisms?

Back

Examples of traits that can vary include paw size, whisker thickness, beak thickness, and tongue length.

Front

What is the role of genes in determining traits?

Back

Genes provide the instructions for making proteins, which in turn influence the development of physical traits.

Front

What happens if two organisms have different proteins for the same trait?

Back

If two organisms have different proteins for the same trait, they will likely exhibit different physical characteristics.

Front

What is the relationship between proteins and traits?

Back

Proteins are the molecules that express traits; different proteins can lead to different expressions of the same trait.

Front

Why might two offspring from different parents have different traits?

Back

Two offspring from different parents may have different traits due to the unique combination of genes inherited from each parent.
