Traits and Reproduction Review

Front

What are genes?

Back

Genes are segments of DNA that contain the instructions for building proteins, which determine traits in living organisms.

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 affect traits?

Back

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

Front

What is the role of proteins in cells?

Back

Proteins perform a variety of functions in cells, including structural support, transport, and catalyzing biochemical reactions.

Front

What is the difference between dominant and recessive genes?

Back

Dominant genes express their traits even if only one copy is present, while recessive genes require two copies to express their traits.

Front

What is phenotype?

Back

Phenotype refers to the observable physical and biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is genotype?

Back

Genotype is the genetic constitution of an organism, representing the specific alleles inherited from its parents.

Front

How do offspring inherit traits from their parents?

Back

Offspring inherit traits through the combination of alleles from both parents, which are passed down through their genes.

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 and can lead to evolution.

Front

What is the relationship between genes and proteins?

Back

Genes provide the instructions for making proteins, and the specific sequence of a gene determines the structure and function of the resulting protein.
