In some carnations, flower color exhibits codominance. When crosses, Red (R) and white (W) flowers make speckled flowers (RW) that show both colors.
Complete a cross between A speckled flower and a red flower. Find the phenotype ratio.

• 2 red: 2 speckled: 0 white
• 4 red: 0 speckled: 0 white
• 0 red: 4 speckled: 0 white
• 0 red: 2 speckled: 2 white

If a gene is found only on the X chromosome and not the Y chromosome, it is said to be what?

• sex-linked trait
• polygenic trait
• codominant trait
• incomplete dominance trait

A single gene has 3 or more alternative forms. These are called

• heterozygotes

• multiple alleles

• epistatic

• polygenic

This is when a trait is controlled by more than one gene.

• Multiple alleles
• Polygenetic inheritance
• Codominance
• Incomplete Dominance
