Key Concepts
Law of Segregation
During gamete formation, the two alleles for each gene segregate from each other so that each gamete carries only one allele for each gene.
Genotype vs Phenotype
Genotype is the genetic makeup (e.g., Aa), while Phenotype is the physical expression of the trait (e.g., Brown Eyes).
Dominant & Recessive
Dominant alleles (A) mask recessive alleles (a). Recessive traits only appear if the genotype is homozygous recessive (aa).
Learn Mendelian Genetics with Punnett Squares
**Genetics Probability** is the mathematical prediction of inheritance patterns. By utilizing an interactive **Punnett Square**, we can visualize how the **Law of Segregation** governs the distribution of alleles from parents to their progeny.
In a standard **Monohybrid Cross**, each cell in the 2×2 grid represents a potential offspring **Genotype** (the genetic makeup, e.g., AA, Aa, or aa). This genotype directly dictates the **Phenotype**, which is the observable physical trait, such as eye color or height.
Use this tool to simulate crosses and analyze **Dominant** and **Recessive** inheritance frequencies, allowing you to master classic Mendelian ratios and predict the outcome of biological breeding experiments.
