Stronger Gene – One that appears when the allele is present

Capital letter

Example: T - Tall

• Recessive Allele

• Dominant Allele

• Heterozygous

• Homozygous

Weaker gene – One that can be hidden by the another allele

Lowercase letter

Example: t - short

• Homozygous

• Heterozygous

• Dominant Gene

• Recessive Allele
