Grade 6 Heredity Quiz: Test Your Knowledge of Inherited Traits

🧬 Quick Study Guide

• 🌱 Heredity: The passing of traits from parents to offspring.
• 🧩 Traits: Characteristics like eye color, hair color, or height.
• 🧬 Genes: Units of heredity made of DNA. They determine specific traits.
• 🔬 Alleles: Different forms of a gene (e.g., allele for blue eyes and allele for brown eyes).
• dominant and recessive alleles: A dominant allele expresses its trait even if a recessive allele is present. A recessive allele only expresses its trait if two copies are present.
• 👨‍👩‍👧‍👦 Genotype: The genetic makeup of an individual (e.g., BB, Bb, bb).
• 👀 Phenotype: The observable characteristics of an individual (e.g., brown eyes, blue eyes).
• ➗ Punnett Square:** A diagram used to predict the possible genotypes and phenotypes of offspring.
