This trait always shows up in an organism when the allele is present

• dominant allele
• codominance
• probability
• recessive allele

This trait is hidden whenever the dominant allele is present

• dominant allele
• codominance
• recessive allele
• Punnett Square

A chart that shows all the possible combinations of alleles that can result from a genetic cross

• dominant allele
• codominance
• probability
