Gregor Mendel Achievements
Mendel used to conduct his very famous hereditary experiments in his free time. He did something no one had ever done before and no one ever had analyzed statistically the experiments of breeding. It was Mendel’s knowledge of natural sciences and his studies that helped him carry out these experiments. He usually chose to work with pea plants and selected only those ones that were cultivated in controlled atmosphere and were a pure variety. He cross bred many seeds and then found out results of the seven most evident seeds and variations.

It was concluded by Mendel that short plants created only short heighted off springs while tall plants gave both short and long plants. He also discovered that only one third of the long heighted plants gave long heighted off springs so he figured out that long plants were of two types, ones that gave bred true plants and the others that did not bred true plants.

Mendel continued with his experiments. He thought that he’d find more about the off springs by cross breeding the plants of different sizes. He thought that by crossing a long plant and a small plant, a plant of medium size would be produced but later on he found out that was not true. Mendel crossed different plants and calculated the results. He planted some plants with the cross of long and short plants and then planted the seeds of some long plants and pollinated some of them himself.

As a result, the naturally pollinated plants from the cross of short-long plants were long and the ones of long plants that were unnaturally pollinated sprouted short. The tallness of the plant which is said to be the most overpowering feature was said to the dominant trait while the shortness was known as the recessive trait. The results did not vary whether a male plant was used or a female plant. This investigation of Mendel’s took more than eight years to finish and it almost included 30,000 plants or more.

The law of segregation which is the first heredity law was based

    How are traits passed down from one generation to the next? Does the genes from both parent combine into 1 or are the inherited by a whole where 1 is express while the other stays dormant. Using Mendel’s Laws as a base for our experiment, we will determine the expected outcome of these traits to help determine how genes are passed down. We will learn see if genes are randomly passed down and which genes of the parents are more likely to be expressed in the off springs. If the genes are passed down as a whole, then how can we tell which gene is the dominant and the recessive trait. How can reproducing an experiment similar to the pea pod plant can help us answer the question and support our hypothesis? In this experiment we will learn terms and definitions related to Mendel’s Law and comparing the actually experiment’s outcome compared to the data expected by Mendel’s Laws.…

    B is dominant to b, so offspring with either the BB or Bbgenotype will have the purple-flower phenotype. Only offspring with the bbgenotype will have the white-flower phenotype. Therefore, in this cross, you would expect three out of four (75 percent) of the offspring to have purple flowers and one out of four (25 percent) to have white flowers. These are the same percents that Mendel got in his first experiment.…

    This lab was testing different methods to prevent bean beetles form infesting a chickpea harvest. They wanted to find something that would protect the crop from this invasive creature. To do this they created 3 replicate experiments which contained 25g of seeds each group with a different genotype, and 5 newly hatched adult C. maculatus were added to the jar. They continued to check this on a weekly basis, at the end of the experiment they found that the results where quite different for each jar, and that all of them were not immune to the bean beetle.…

    Plant sexuality has a wide range of topics about sexual reproduction systems found across the plant kingdom. Flowers, which are the reproductive units of angiosperms, amongst all living things are physically varied the most. They also show the greatest diversity in methods of reproduction of all biological systems. The system for classifying flowering plants was proposed by Carolus Linnaeus, which is based on plant structures. Plants employ several different morphological adaptations that involve sexual reproduction. Christian Konrad Sprengel studied plant sexuality, which brought understanding to the pollination process. This process involved both biotic and abiotic…

    This experiment, which was used to explore the Theory of Evolution created by Charles Darwin. The use of natural selection was apparent in the artificial modification of an organism's traits which aided in this investigation. Through this experiment the Wisconsin Fast Plant was used. It is a fast-growing organism developed to improve the resistance to disease in cruciferous plants. This plant aids scientist in the exploration of environmental effects on population due to the speed to which is matures and reproduces. Artificial selection was stimulated by the selection against plants with few hairs(trichomes). Trichomes create a wider variation which means it is polygenic. The plants that had only a few trichomes were exterminated and the rest were pollinated to create an F2 generation. This was done in an attempt to increase the number of plants with many hairs in the next generation. It turned out to be a successful use of natural selection due to the decreased amount of bald plants from the F1 generation to the F2 generation.…

    Gregor Mendel wondered is his principle of segregation worked with individuals who differed in two traits. To test this, Mendel crossed pure lined round, yellow seeds with pure lined wrinkled, green seeds. He predicted that the F_1 offspring would be heterozygous for both genes. Experiments had established that the allele for yellow seeds were the dominant allele (Y) and green seeds were the recessive allele (y). There were two different ways as to how seed shape and seed color would be passed onto offspring. One was independent assortment, which says that the allele for seed shape and the allele for seed color present in each parent would assort independently. Another was dependent assortment, which says that the alleles for seed color and…

Concerning how the experiment is actually performed, five Wisconsin fast seeds are planted into a cup full of soil and six fertilizer seeds. The seeds are then covered with more dirt and connected to a cup full of water through a wick. The soon to be plant is then placed under light for 24 hours. After this the plants with the highest amount of trichome numbers are found and kept. When flowers are present, the selected plants are cross pollinated with a pollinating stick and from there the plants are monitored and recorded.…

    Mendel was the first to see that traits in each person were passed down, not just from the parents, but also from grandparents, great-grandparents, great-great-grandparents, etc. He also figured out that not every person is the same as his or her own parents. Some of these traits can come from other family members that are no longer living. Mendel is the first to also describe these traits as passages through the generations. There are at least three reasons for Mendel’s success; 1) He focused on just a few traits – seven to be exact – instead of many traits as others did; 2) he thoroughly documented and quantified all of his experimental results; and 3) he chose to study these traits in the garden pea, Pisum sativum.…
