• polygenic trait
• codominant trait
• incomplete dominance trait

Multiple Choice

Why are men 16 times more likely to be color-blind than women?

• to be color-blind, you must have a Y chromosome
• to be color-blind, all of your X chromosomes must have the gene
• color-blindness is caused by testosterone
• color-blindness is caused by the same gene as baldness

Multiple Choice

Males are more likely to suffer from a sex-linked disease or disorder because

• males are the weaker sex
• males have less DNA
• males have 1 X chromosome, so the disorder is more likely to be expressed

Multiple Choice

• The X chromosome has many more genes
• The Y chromosome has many more genes
