Mendel's experiments with pea plants were really important for understanding genetics. He studied how traits are passed down, and his work helped shape modern genetics. Let's break down his discoveries:
Law of Segregation: Mendel found out that during the process of making gametes (which are the cells used in reproduction), genes separate. This means each gamete only carries one gene for each trait. He showed this through his experiments where he crossed pea plants, leading to a pattern where he found 3 plants with a certain trait for every 1 plant without it in the next generation.
Law of Independent Assortment: Mendel also showed that the way one trait is inherited doesn’t affect how another trait is inherited. He tested this with two traits at once and found a pattern where different traits combined in a specific way, producing a ratio of 9:3:3:1 in the offspring for two plants that each carried both traits.
Quantitative Analysis: Mendel kept careful notes on his experiments, which helped him understand which traits were dominant (stronger) and which were recessive (weaker). For instance, in his studies, he saw that 75% of the plants in one generation showed the dominant traits.
Overall, Mendel's work showed that traits are passed down in predictable ways. He helped us understand genetic inheritance, which later opened the door to new fields like molecular genetics, genomics, and biotechnology. Today, we know that humans have about 20,000 to 25,000 genes, and his studies helped explain how such a variety of traits and characteristics can be inherited.
