  2. 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.

  3. Experiments on Plant Hybridization - Wikipedia

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

    Modern geneticists have inferred the 7 genes studied by Mendel. It is impossible to know for certain, but the identification is possible to a high degree of confidence based on Mendel's description, and the pea varieties grown in central Europe in the 1850s. [5] The table shows that the 7 genes appeared on 5 chromosomes.

  4. Pea - Wikipedia

    [60] [61] He ended up growing and examining about 28,000 pea plants in the course of his experiments. [62] Mendel chose peas for his experiments because he could grow them easily, pure-bred strains were readily available, [63] and the structure of the flowers protect them from cross-pollination, and cross pollination was easy. [64]

  5. Mendelian inheritance - Wikipedia

    en.wikipedia.org/wiki/Mendelian_inheritance

    He then conceived the idea of heredity units, which he called hereditary "factors". Mendel found that there are alternative forms of factors—now called genes—that account for variations in inherited characteristics. For example, the gene for flower color in pea plants exists in two forms, one for purple and the other for white.

  6. 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)

    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.

  8. Plant genetics - Wikipedia

    en.wikipedia.org/wiki/Plant_genetics

    The discoverer of genetics was Gregor Mendel, a late 19th-century scientist and Augustinian friar. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring. He observed that organisms (most famously pea plants) inherit traits by way of discrete "units of inheritance".

  9. 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 ...
