Match the term with its definition:

• Expressed trait in the presence of another

• Multiple alleles

• Having 2 identical alleles for a trait

• Recessive

• Trait that is masked by a dominant trait

• Gene

• Matching genes; 1 - father & 1 - mother

• Allele

• Factors that control the traits

• Dominant

Match the term with its correct definition:

• The observable characteristics of an organism

• Genotype

• Characteristic such as height; >2 genes

• Homozygous

• Having two different alleles for a trait

• Polygenic Trait

• Having two identical alleles for a trait

• Heterozygous

• The genetic makeup of an organism

• Phenotype

Match the term with it's definition:

• The transmission of genetic traits from both parents to offspring.

• Incomplete dominance

• A situation in which neither allele is dominant, resulting in a blend of traits.

• Epigenetics

• How cells control gene activity wout DNA

• Maternal & Paternal Inheritance

• 3 base mRNA codes for 1 amino acid

• Codon

• A genetic scenario where both alleles are expressed equally.

• Codominance
