Gregor Mendel did his experiments because he was looking to see how genetics and heredity worked. He used pea plants because they bred true. He found that the taller plants all produced tall plants if they were self pollinated. If short plants were used and were cross pollinated, they would all be short.

What scientist discovered some basic rules about inheritance?
Gregor Mendel, an Austrian monk, is credited with discovering the basic rules of inheritance through his experiments on pea plants in the mid-19th century. Mendel's work laid the foundation for modern genetics and our understanding of how traits are passed down from one generation to the next.
What conclusions did Morgan arrive at with his experiments on fruit flies and why did they extend Mendel's conclusions?
Morgan concluded that genes are located on chromosomes and that some genes are linked to specific traits. He extended Mendel's conclusions by demonstrating that genes are physically located on chromosomes and can be inherited as a unit, leading to the concept of gene linkage and genetic recombination.
What was Mendel's results to his first experiment?
In Mendel's first experiment with pea plants, he crossed true-breeding plants with contrasting traits (e.g., tall and short). He found that the first generation (F1) offspring all displayed one of the traits, while the second generation (F2) showed a 3:1 ratio of the dominant to recessive trait. This led him to formulate his principles of inheritance, now known as Mendelian genetics.
How are autosomal traits related to Mendel's observations of heredity?
Gregor Mendel grew hundreds of pea plants. He was curious as to why some of the plants had different traits. Some plants were tall and others were short. Some plants produced green seeds while others produced yellow seeds.Mendel observed that most of the pea plants' traits were similar to its parents. In this observation, Mendel discovered heredity. Heredity is the passing of traits from parents to offspring.Mendel started his experiments with purebred plants, a plant that always produces offspring with the same form of a trait as a parent. Purebred pea plants self-pollinate (pollinate by themselves.) The pistil produces female egg cells. And the stamens produce pollen that contains male sex cells.Next, Mendel cross-pollinated the plants. He took the pollen from a short plant and applied it to a tall plant. He called this generation the parental generation or the P generation. The offspring of this generation was called the first filial generation. The offspring of this first filial generation were all tall. Mendel was curious as to why the tall plant gene over powered the short plant gene. It was because in pea plants tall genes are the dominant allele while short genes are the recessive allele.When the pea plants from the first filial generation were pollinated, three-fourths of the offspring (called the second filial generation) were tall and one-fourth was short. It showed Mendel that recessive alleles can reappear in the next generation of plants.Some Key AbbreviationsT = dominant allelet = recessive alleleTT = (purebred) a plant that inherited two dominant allelesTt = (hybrid) a plant that inherited one dominant allele and one recessive allelett = (purebred) a plant that inherited two recessive alleles
How did people explain how traits came from parents before Mendel's experiments?
People believed that the parents genes mixed (like paint) to create an offspring of similar resemblence in some ways. Be mindful that this was before dominant and recessive traits came about, which im sure you already know. Thanks for asking! Hope that clears it up! - K.C
What were Gregor Mendel's first two experiments?
Gregor Mendel's first experiment was with pea plants. His goal was to find the genetic qualities in the third generation and see how they differ with the parental generation. He later developed some twisted logic about DNA. You can simulate Mendel's experiment with a Punnet Square and some data.
What are some What are facts about Gregor Mendel?
He was a monk. He knew nothing of DNA or genetics when doing his experiments.
What was some of the work of others that Mendel used as background information for his experiments?
During his college work, Mendel studied under Johnann Nestler, who did research on breeding sheep for maximum output of wool. From this, Mendel saw that specific traits could be passed from one generation to the next. His work at the abbey gave this idea a scientific foundation that, amazingly, was lost for almost 40 years.

What is the kind of trait that seemed to vanish in the offspring produces in Mendel's first experiment?
Mendel's experiments showed the characteristics of genes that express complete dominance--that is, traits where one allele is completely dominant over another, and the recessive allele does not appear in the phenotype at all. Some of the specific traits that Mendel was testing include pea color (yellow or green, with green being completely dominant) pea surface texture (wrinkled or smooth, with smooth being dominant) and flower color (pink and white, with pink being dominant.)
What conclusions did Morgan arrive at with his experiments on fruit flies and why did they extend Mendel's conclusions?

What are some of gregor Mendel's intrests?
While a student, physics and astronomy were Mendel's greatest interests. However, he was unable to get certified as a teacher in that field, so he began work at an abbey. While there, his interest in inherited traits (which came to him during his college studies) resulted in his experiments on that subject.

What are the inventions of Gregor Mendel?
Gregor Mendel is called the father of genetics. He was a monk who studied pea plants to find out about genetics. He discovered many new things.A:Discovered the dominant and recessive mode of genetic inheritance A:http://www.biojuris.com/natural/index.html (Exact quote) Gregor Mendel was carrying out experiments that would establish the foundation of modern genetics. In the classic experiments on peas performed by Mendel from 1857 to 1863, he found that each physical trait of the plant was controlled independently by its own unique pair of factors that he called elementen. These elementen are now known as genes. Each parent packages half of its genes into its gamete, the egg and sperm. Upon fertilization and conception, the embryo offspring inherits equal parts of its mother's and father's genes. The importance of Mendel's work went completely unrecognized during his lifetime. It wasn't until the early twentieth century when a new generation of scientists began to unravel the mechanism of heredity that the buried genius of his work was discovered.

What historical factors have an impact on the existence of domestic violence in our present society?
When the economy is in a recession, cases of domestic violence increase. Culturally, some people have always had it in their lives and they continue it generation after generation.
What was some great things that Gregor Mendel did?
Gregor Mendel was an Austrian monk and scientist known as the father of modern genetics. He formulated the laws of inheritance by conducting groundbreaking experiments with pea plants, laying the foundation for the field of genetics. His work established the principles of genetic heredity and greatly influenced the study of genetics and biology.
