Experiments on Plant Hybridization" (German: Versuche über Pflanzen-Hybriden) is a seminal paper written in 1865 and published in 1866 [1] [2] by Gregor Mendel, an Augustinian friar considered to be the founder of modern genetics. The paper was the result after years spent studying genetic traits in Pisum sativum, the pea plant.
Mendel selected for the experiment the following characters of pea plants: Form of the ripe seeds (round or roundish, surface shallow or wrinkled) Colour of the seed–coat (white, gray, or brown, with or without violet spotting) Colour of the seeds and cotyledons (yellow or green) Flower colour (white or violet-red)
Mendel was assisted in his experimental design by Aleksander Zawadzki while his superior abbot Napp wrote to discourage him, saying that the Bishop giggled when informed of the detailed genealogies of peas. [27] After initial experiments with pea plants, Mendel settled on studying seven traits that seemed to be inherited independently of other ...
Between 1856 and 1865, Gregor Mendel conducted breeding experiments using the pea plant Pisum sativum and traced the inheritance patterns of certain traits. Through these experiments, Mendel saw that the genotypes and phenotypes of the progeny were predictable and that some traits were dominant over others. [14]
Mendel then chose to further his experiments by crossing a pea plant homozygous dominant for round and yellow phenotypes with a pea plant that was homozygous recessive for wrinkled and green. The plants that were originally crossed are known as the parental generation, or P generation, and the offspring resulting from the parental cross is ...
The traits observed in this cross are the same traits that Mendel was observing for his experiments. This cross results in the expected phenotypic ratio of 9:3:3:1. Another example is listed in the table below and illustrates the process of a dihybrid cross between pea plants with multiple traits and their phenotypic ratio patterns.
Gregor Mendel (1822–1884) was an Austrian monk who theorized basic rules of inheritance. [4] From 1858 to 1866, he bred garden peas (Pisum sativum) in his monastery garden and analyzed the offspring of these matings.
Gregor Mendel, the Father of Genetics William Bateson Ronald Fisher. Particulate inheritance is a pattern of inheritance discovered by Mendelian genetics theorists, such as William Bateson, Ronald Fisher or Gregor Mendel himself, showing that phenotypic traits can be passed from generation to generation through "discrete particles" known as genes, which can keep their ability to be expressed ...
