Step into the world of Gregor Mendel, the father of modern genetics, and challenge your understanding of how traits are passed from one generation to the next. This quiz will take you through the essential concepts of Mendelian genetics, including dominant and recessive alleles, genotype and phenotype ratios, and the laws of inheritance. Sharpen your knowledge and see how well you grasp the principles that form the foundation of genetics.
