Gregor Mendel was a scientist who did experiments that helped us understand how traits are passed down from parents to their kids. This is what we now call genetics. In the 19th century, he worked with pea plants and made some important discoveries about inheritance. Let’s break down how his experiments changed our view:
Mendel found some main ideas about how traits are inherited, which shifted what we thought before:
Dominance: He learned that some traits are stronger than others. For example, in pea plants, the gene for purple flowers (P) is stronger than the gene for white flowers (p). If you take a plant with two purple flower genes (PP) and cross it with a plant that has two white flower genes (pp), all the baby plants will have purple flowers (Pp).
Law of Segregation: This law says that when plants create seeds, their genes for a trait split up. This means each seed gets only one gene from each trait. Mendel showed that these genes come together again when fertilization happens.
Law of Independent Assortment: This idea explains that one pair of genes separates independently from another pair. For example, just because a plant has a certain flower color doesn’t mean it will have a specific height too.
Mendel carefully mixed pea plants and kept track of their traits over many years. Here’s how he did it:
Counting Results: He counted how many times each trait appeared, which helped him create his laws. For example, he noticed that in the second generation of plants, there was often a 3:1 ratio of dominant traits to recessive traits.
Control over Crosses: By deciding which plants could mate, Mendel avoided confusing results and focused on clear outcomes.
At first, people didn’t pay much attention to Mendel’s work. But later, his findings became very important for modern genetics. He showed that:
Overall, Mendel’s experiments changed the way we study living things. They taught scientists that inheritance isn’t just random but follows certain rules. This helps us learn more about the variety of life on Earth and how species evolve. His contributions are still influencing many fields today, from farming to medicine, showing how important those pea plants really were!
