  2. Monohybrid cross - Wikipedia

    en.wikipedia.org/wiki/Monohybrid_cross

    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)

  3. Plant genetics - Wikipedia

    en.wikipedia.org/wiki/Plant_genetics

    Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. [ 1 ] [ 2 ] It is generally considered a field of biology and botany , but intersects frequently with many other life sciences and is strongly linked with the study of information systems .

  4. Gregor Mendel - Wikipedia

    en.wikipedia.org/wiki/Gregor_Mendel

    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.

  5. Mendelian inheritance - Wikipedia

    en.wikipedia.org/wiki/Mendelian_inheritance

    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 ...

  6. Punnett square - Wikipedia

    en.wikipedia.org/wiki/Punnett_square

    The Punnett square is a visual representation of Mendelian inheritance, a fundamental concept in genetics discovered by Gregor Mendel. [10] For multiple traits, using the "forked-line method" is typically much easier than the Punnett square.

  7. Dihybrid cross - Wikipedia

    en.wikipedia.org/wiki/Dihybrid_cross

    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 ...

  8. Experiments on Plant Hybridization - Wikipedia

    en.wikipedia.org/wiki/Experiments_on_Plant...

    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.

  9. Pleiotropy - Wikipedia

    en.wikipedia.org/wiki/Pleiotropy

    Pleiotropic traits had been previously recognized in the scientific community but had not been experimented on until Gregor Mendel's 1866 pea plant experiment. Mendel recognized that certain pea plant traits (seed coat color, flower color, and axial spots) seemed to be inherited together; [3] however, their correlation to a single gene has never been proven.
