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 ...
The garden pea was chosen as an experimental organism because many varieties were available that bred true for qualitative traits and their pollination could be manipulated. The seven variable characteristics Mendel investigated in pea plants were. [5] seed texture (round vs wrinkled) seed color (yellow vs green) flower color (white vs purple)
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 pistil plant and the pollen plant are both F 1-hybrids with genotype "B b". Each has one allele for purple and one allele for white. In the offspring, in the F 2-plants in the Punnett-square, three combinations are possible. The genotypic ratio is 1 BB : 2 Bb : 1 bb. But the phenotypic ratio of plants with purple blossoms to those with ...
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.

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 ...
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
