Gregor Mendel studied plants.
Gregor Mendel was a man who loved plants.
He looked at many different traits. He saw how plants grew tall or short. He saw different colors on the seeds. 
Mendel wanted to know how traits pass down. He crossed yellow peas with green peas. The first group of babies was all yellow. But then, green peas came back later!
This happened because of hidden rules. Some traits are strong and show up fast. Other traits are quiet and hide for a while. Mendel found these rules by studying many plants.
His work helped us learn how life works. We call his work the start of science for traits. He was a very smart gardener.
Gregor Mendel was a monk and a scientist. 
Between 1856 and 1863, he studied about 28,000 plants. He looked at seven different traits. These included plant height and seed color. Mendel found that some traits are dominant. A dominant trait is strong and shows up easily. Other traits are recessive. A recessive trait is quiet and can stay hidden for a time.
For example, Mendel crossed yellow peas with green peas. The first group of baby plants was all yellow. But the green color came back in the next group! He showed that these traits follow set rules. He called these rules the laws of inheritance. These rules are caused by tiny things we now call genes.
Most people did not understand his work at first. His big ideas were not famous until the year 1900. After that, many scientists studied his rules. Today, we call him the father of modern genetics.
Gregor Mendel was a scientist who changed how we see life. He is often called the father of modern genetics. Genetics is the study of how traits pass from parents to their children. Mendel lived in the Austrian Empire, which is now the Czech Republic. He was also an Augustinian friar and an abbot at St. Thomas' Abbey in Brno. 
To find these rules, Mendel studied pea plants in a garden. He looked at seven different traits in the plants. These included plant height and flower color. He also looked at seed shape and pod color.
Between 1856 and 1863, Mendel grew about 28,000 plants. He used these plants to see how traits move. For example, he crossed a yellow pea with a green pea. The first group of baby plants was all yellow. This happened because yellow is a dominant trait. A dominant trait is one that shows up easily. The green trait is recessive, which means it can stay hidden. In the next generation, the green color came back!
Mendel first shared his work in 1865. He published his paper in 1866. However, most scientists did not understand his big ideas at that time. His work was mostly ignored for many years. It was not until 1900 that his ideas were rediscovered. Three scientists named Erich von Tschermak, Hugo de Vries, and Carl Correns all found his results again. They worked independently to prove his laws were correct. This discovery started the modern age of genetics.
Mendel's life was full of hard work and learning. He was born in 1822 to Anton and Rosine Mendel. He studied physics and philosophy at the University of Olomouc. He even studied under the famous scientist Christian Doppler in Vienna. Mendel became an abbot in 1867, but his duties became very heavy. He died in 1884 at the age of 61. Today, we use his laws to understand all living things. His small garden experiments helped explain the whole world.
Gregor Johann Mendel was an Austrian biologist and mathematician. He is widely known as the founder of modern genetics. Genetics is the study of how biological traits are passed from parents to offspring. Mendel was also an Augustinian friar and the abbot of St. Thomas' Abbey in Brno. 
Mendel's work relied on a process called hybridization. This involves crossing two different varieties of a plant to see the results. He chose to study the pea plant, known as *Pisum sativum*. He focused on seven specific characteristics. These included plant height and flower position. He also studied flower color and pod shape. Other traits included pod color, seed shape, and seed coat tint.
To find these patterns, Mendel conducted massive experiments between 1856 and 1863. He cultivated and tested approximately 28,000 plants. He observed how traits appeared in different generations. For example, he crossed a true-breeding yellow pea with a green one. In the first generation, all the offspring had yellow seeds. The green trait seemed to have vanished entirely. However, the green color reappeared in the next generation. This happened at a specific ratio of one green to three yellow seeds.
Mendel used new terms to explain these observations. He called the traits that show up easily "dominant." He called the traits that can stay hidden "recessive." He proposed that these traits were controlled by invisible "factors." We now call these factors genes. His work established the Law of Segregation and the Law of Independent Assortment. These are now known as the laws of Mendelian inheritance.
Mendel's life was marked by both academic struggle and religious service. He was born in 1822 into a German-speaking family in Silesia. He studied physics and philosophy at the University of Olomouc. He also studied in Vienna under the physicist Christian Doppler. Mendel became a monk to afford his education. He joined the Order of Saint Augustine and took the name Gregor. In 1867, he became the abbot of his monastery. This role brought many administrative duties that eventually limited his scientific research.
Despite his brilliance, the scientific community ignored Mendel for decades. He published his findings in 1866, but they had little impact. His paper was cited only three times in thirty-five years. Even Charles Darwin was unaware of Mendel's specific work. It was not until 1900 that his laws were rediscovered. Three scientists—Hugo de Vries, Carl Correns, and Erich von Tschermak—independently verified his findings. This rediscovery ushered in the modern age of genetics. 
Mendel died in 1884 at the age of 61. He passed away from chronic nephritis in Brno. His scientific legacy grew much larger after his death. In the early 20th century, scientists debated between Mendelians and biometricians. The Mendelians focused on biological understanding, while biometricians used statistical methods. Eventually, these two views were combined. This led to the modern synthesis of evolutionary biology in the 1930s and 1940s. Today, we recognize Mendel as a pioneer who unlocked the secrets of life.
