Genetics is defined as the study of heredity, or the passing of traits from parent to offspring. Known as the Father of Genetics, Gregor Mendel, through his research with garden peas, contributed much to the field of Genetics with his three laws: the Law of Segregation, the Law of Independent Assortment, and the Law of Dominance (“Mendelian Laws of Inheritance” n.d.). Mendel’s research was centered on the physical attributions, or phenotype, of pea plants passed from parent to offspring, such as seed color, seed shape, flower color, etc. Mendel selectively cross pollinated purebred plants with particular phenotypic traits and recorded the outcomes over generations. This experiment became the basis of the nature of genetic inheritance ("Basic Principles of Genetics” n.d.). Although Mendel’s research revolved around plants, his conclusions on heredity are applied to all living things. …show more content…

This gives the outcome of the passing of one trait from parent to offspring. Through his experiment results, Mendel was able to determine the phenotypic and genotypic ratios of both the F1 (filial 1) and F2 (filial 2) generations.
When the F1 generation are heterozygous for each trait, the known outcome of the monohybrid cross for the F2 is a 1:2:1 genotypic ratio, which represents the heterozygous and homozygous (dominant and recessive) alleles, and a 3:1 phenotypic ratio where the dominant trait is present three times as much as the recessive

    In order to figure out the genes responsible, there are several other factors that must be determined. These factors include the number of genes involved, if each gene is x-linked or autosomal, if the mutant or wild-type allele for each is dominant, and if genes are linked or on different chromosomes. Proposed crosses include reciprocal crosses between the pure-breeding mutants of strains A and B with the wild-type will help determine if the genes or sex-linked or autosomal, in addition to which alleles are dominant (8). Another proposed cross includes complementation crosses between pure-breading mutants from strains A and B to determine if one or two genes are involved (8). Furthermore, testcrosses between F1 progeny and pure-breeding recessive mutants from strains A and B, which will help determine if genes are linked on the chromosome or if they assort independently (8). These proposed crosses are shown in the attached

    651 Words  | 2 Pages

    The purpose of our experiment was to test whether or not the Wisconsin Fast Plants, or Brassica rapa, followed the Mendelian genetics and its law of inheritance. First, after we crossed the heterozygous F1 generation, we created an F2 generation which we used to analyze. After analyzing our results, we conducted a chi-square test for for both the F1 and F2 generations to test their “goodness of fit”. For the F1 generation we calculated an x2 value of 6.97, which was greater than the value on the chi-square table at a p-value of 0.05 and 1 degree of freedom (6.97 > 3.84). This meant that we had to reject our hypothesis that stated there would be no difference between the observed and expected values. This showed us that the F1

  • Apterous Experiment

    In this experiment, Mendelain Models are observed. The purpose of the experiment is to understand how traits are passed from one generation to the other as well as understanding the difference between sex linked and autosomal genes. One particular trait that is observed in this experiment is when a fly is lacking wings, also known as an apterous mutation. In this experiment, we will determine whether this mutation is carried on an autosomal chromosome or on a sex chromosome. The data for this experiment will be determined statistically with the aid of a chi-square. If the trait is autosomal, then it will be able to be passed to the next generation on an autosomal chromosome, meaning that there should be an equal amount of male and

  • Examining the Crosses Between Drosophila Fruit Flies

    613 Words  | 2 Pages

    The major topic of this experiment was to examine two different crosses between Drosophila fruit flies and to determine how many flies of each phenotype were produced. Phenotype refers to an individual’s appearance, where as genotype refers to an individual’s genes. The basic law of genetics that was examined in this lab was formulated by a man often times called the “father of genetics,” Gregor Mendel. He determined that individuals have two alternate forms of a gene, referred to as two alleles. An individual can me homozygous dominant (two dominant alleles, AA), homozygous recessive, (two recessive alleles, aa), or heterozygous (one dominant and one recessive allele, Aa). There were tow particular crosses that took place in this experiment. The first cross-performed was Ebony Bodies versus Vestigle Wings, where Long wings are dominant over short wings and normal bodies are dominant over black bodies. The other cross that was performed was White versus Wild where red eyes in fruit flies are dominant over white eyes.

  • Gregor Mendel's Theory Of Heredity

    265 Words  | 1 Pages

    Heredity was a concept that little was known about before the 20th century. In that era, there were two main concepts that most followed about heredity. First, that heredity occurred within a species, and second, that traits were given directly from parents to offspring. These ideas led people to believe that inheritance was the result of a blend of traits within a fixed, unchanging species. In 1856, Gregor Mendel began his experiments in which he would discover the basic underlying principles of heredity.

    Biologist, Gregor Johann Mendel, discovered how traits passed from one generation to the next. Mendel studied and used pea plants to discover the principles that rule heredity. He found that each parent, father, and mother pass down traits to their offspring, who inherit different combinations of their recessive or dominant alleles-terms introduced by Mendel during the 19th century. Mendel introduced important principles teaching us that recessive traits will only be shown in the phenotype if both alleles are recessive. Mendel’s laws of inheritance include the Law of segregation and the Law of independent assortment.

They believe that they have discover some life changing information. They had this discovery for a while now but that needed time to gather up all of the facts from their research. This information that they have could transform our view on the world. They have revealed some type of time machine that has allow them to see back in ancient history. For that past ten years this man and his team have been using this time machine to gather all types of different information about the past history. This information came for just once source, blood.

    Evolution is the reason for many different species and their existence. Evolution proves that there is much more to the world than the human can see. Charles Darwin had looked into the eye of the storm, and found something revolutionary. His research has changed and reshaped science in it’s own very existence; changing how scientists see their works. Charles created a new way of thinking, and proven that there is always an alternate reason why something is the way it is, and how it became that way, not to mention he constructed against religion that proves itself to be wrong. Everything has a reason, and evolution has made that reason clear to us, through Darwin’s works.”Charles Darwin is best known for his work as a naturalist, developing a theory of evolution to explain biological change.”

    Genetic testing has become very popular as technology has improved, and has opened many doors in the scientific community. Genetic testing first started in 1866 by a scientist known as, Gregor Mendel, when he published his work on pea plants. The rest was history after his eyes opening experiments on pea plants. However, like any other scientific discovery, it bought conflicts which caused major controversies and a large population disagreed with the concept of playing with the genetic codes of human beings. Playing God was the main argument that people argument that people had against genetics. genetic testing became one of the major conflicts conflicts to talk about, due to the fact that parents could now have the option of deciding if they

He is remembered for paving the way for scientists and future generations to come. Unfortunately, Mendel’s work went unnoticed until 16 years after his death and 34 years after he published his research. Though Mendel lay covered in his grave, his work would eventually be uncovered. Although Mendel was not there to see it,
