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.
A Punnett square showing a typical test cross. (green pod color is dominant over yellow for pea pods [1] in contrast to pea seeds, where yellow cotyledon color is dominant over green [2]). Punnett squares for each combination of parents' colour vision status giving probabilities of their offsprings' status, each cell having 25% probability in ...
The predictions of the combinations of the gametes will be constructed on a Punnett square. [citation needed] In conducting a monohybrid cross, Mendel initiated the experiment with a pair of pea plants exhibiting contrasting traits, one being tall and the other dwarf. Through cross-pollination, the resulting offspring plants manifested the tall ...
A Punnett square for one of Mendel's pea plant experiments – self-fertilization of the F1 generation. The Law of Segregation of genes applies when two individuals, both heterozygous for a certain trait are crossed, for example, hybrids of the F 1-generation.
A Punnett square for one of Mendel's pea plant experiments - self-fertilization of the F1 generation, shows that inheritance is particulate, not blending. Further information: Mendelian inheritance and Germ plasm
Mendel worked with seven characteristics of pea plants: plant height, pod shape and color, seed shape and color, and flower position and color. Taking seed color as an example, Mendel showed that when a true-breeding yellow pea and a true-breeding green pea were cross-bred, their offspring always produced yellow seeds.
The idea of a dihybrid cross came from Gregor Mendel when he observed pea plants that were either yellow or green and either round or wrinkled. Crossing of two heterozygous individuals will result in predictable ratios for both genotype and phenotype in the offspring. The expected phenotypic ratio of crossing heterozygous parents would be 9:3:3 ...
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 ...
