Vocabulary Review

Explore the fascinating world of genetics and how characteristics are transmitted from parent to offspring. Learn about Gregor Mendel, the father of genetics, and his experiments with garden peas. Discover terms like genotype, phenotype, dominant, recessive, and more. Dive into the laws of segregation and independent assortment. Use Punnett squares to solve genetics problems and understand the generations of hybrids produced through crossbreeding. Uncover the mysteries of molecular genetics and the role of genes and alleles in determining traits.
