Inherited Traits Quiz with Answers for Grade 7 Biology Students

🧬 Quick Study Guide

• 🌱 Inherited Traits: Characteristics passed from parents to offspring (e.g., eye color, hair color).
• 🧬 Genes: Units of heredity made of DNA, located on chromosomes.
• 🧩 Alleles: Different forms of a gene (e.g., allele for blue eyes, allele for brown eyes).
• 🧮 Genotype: The genetic makeup of an individual (e.g., BB, Bb, bb).
• 👁️ Phenotype: The observable characteristics of an individual (e.g., brown eyes).
• 📜 Dominant Allele: An allele that expresses its trait even when paired with a recessive allele.
• 🗝️ Recessive Allele: An allele that only expresses its trait when paired with another recessive allele.
• ➕ Punnett Square: A diagram used to predict the genotypes and phenotypes of offspring.
