Hey future biologist! Ever wondered how you ended up with your grandma's curly hair and your dad's love for spicy food? Welcome to the fascinating world of genes and how they make us who we are. Today, let's tackle Punnett grids, dihybrid crosses, and Mendel's experiments with peas. 🌱

• Monohybrid Cross: Examines the inheritance of one gene. Like asking, "Will my kid love spicy food like me?"
• Dihybrid Cross: Examines the inheritance of two genes at once. Like asking, "Will my kid love spicy food and have curly hair like me?"

👨‍🔬 Mendel's Pea Experiment: He crossed round yellow peas with wrinkled green peas. All the first-generation (F1) hybrids were round and yellow—dominant traits for the win!

If the F1 hybrids have the genotype RrYy (R=Round, r=wrinkled, Y=Yellow, y=green), they can produce 4 types of gametes (RY, Ry, rY, ry). It's like a genetic dice roll; you have an equal chance of getting any of the four.

How to Make a Punnett Grid 📊

• Genotypes of Parents: Know who the parent plants/animals are, genetically.
• Genotypes of Gametes: Figure out the potential baby-making cells (gametes).
• Draw the Grid: Make a row for each male genotype and a column for each female one.
• Label the Grid: Put those genotypes around the grid to see what's combining with what.
• Fill the Grid: Get those genotypes into the cells!
• Decipher Phenotypes: Translate those genotypes into traits (like eye color, etc.).
• Count 'Em Up: Tally how many of each phenotype you've got.
