Why did Mendel continue some of his experiments to the F2 or F3 generation?

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 was Mendel's results to his first experiment?
He found out that some traits in one generation (parents) was not present in the next generation (offspring).
What are three reasons mendel chose pea plants for his experiments?

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
What did mendel discover about the inheritance traits?
Mendel drew two conclusions. Mendel concluded that biological inheritance is determined by factors that are passed from one generation to the next. Mendel also concluded that the principle of dominance states that some alleles are dominant and others are recessive.
What were two factors responsible for Mendel success?
between 1856 and 1863 mendel cultivated and tested some 28,000 pea plants
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 Mendel's results to his first experiment?
He found out that some traits in one generation (parents) was not present in the next generation (offspring).
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 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 website is Gregor Mendel pictures on?
Try Biography of Gregor Mendel. It has some decent pictures of Mendel and the garden where he planted his peas.
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 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.
When was Some Experiments created?
Some Experiments was created on 2006-03-27.
How did mendel control pollination in his plants?
Mendel was interested in the offspring of two different parent plants, so he had to prevent self-pollination. He removed the anthers from the flowers of some of the plants in his experiments. Then he pollinated them by hand with pollen from other parent plants of his choice. When pollen from one plant fertilizes another plant of the same species, it is called cross-pollination.
