What is the role of proteins in determining traits?

Back

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

What is the difference between dominant and recessive genes?

Back

Dominant genes can mask the effects of recessive genes, meaning that if a dominant gene is present, its trait will be expressed.

What does it mean for genes to be homozygous?

Back

Homozygous means that an organism has two identical copies of a gene for a particular trait.

Front

What does it mean for genes to be heterozygous?

Back

Heterozygous means that an organism has two different copies of a gene for a particular trait.
