NGSS.HS-LS3-1

An allele that is masked when a dominant allele is present. The "weaker" gene. 

• Dominant Allele
• Recessive Allele

An allele whose trait always shows up in the organism when the allele is present. The "stronger" gene. 

• Dominant Allele
• Recessive Allele

An organism’s genetic makeup or allele combination.

• Genotype
• Phenotype
