Hello future biologists! Are you ready to unravel the mysteries of life? Let's dive into the awesomely complex world of genotypes and alleles. We'll make it easy, fun, and relatable. Buckle up!

Key Terms 📚

  • Gene: A segment of DNA that codes for a particular trait.
  • Allele: Different versions of a gene.
  • Genotype: The specific set of alleles an individual has.
  • Mutation: A change in the DNA sequence, resulting in a new allele.
  • Diploid: Having two sets of chromosomes, thus two alleles for most genes.
  • Homozygous: Having two identical alleles for a gene.
  • Heterozygous: Having two different alleles for a gene.
  • Gamete: A reproductive cell (sperm or egg).

Genes & Alleles 👩‍🔬

What's an Allele Anyway?

  • Imagine a gene is a recipe for making cookies. Alleles are like variations of that recipe: chocolate chip, sugar, oatmeal raisin—you get the idea.
  • Real-World Example: Think about eye color; you can have blue, brown, or green eyes. The different eye colors are due to different alleles of the same eye color gene.
