• A trait that appears even if an organism has only one copy of the allele for that trait.

• A trait that can only be seen if an organism has two copies of the allele.

What does it mean if a trait is recessive?

• It is always expressed in the phenotype.

• It is expressed in the phenotype only when two copies of the allele are present.

• It cannot be passed on to offspring.

• It is more common than dominant traits.

If a plant species has a dominant allele "F" that codes for flower color and a recessive allele "f" that codes for no color, what would be the phenotype of a plant with the genotype "ff"?

• Colored flowers

• No flowers

• No color in flowers

• Both colored and uncolored flowers
