200 years of Mendel (part two)
What plant did Gregor Mendel mainly choose for his experiments?
A hint: It’s a legume that’s also in KWS’ portfolio.
200 years of Mendel
An unrecognized genius
Gregor Mendel was born on July 20, 1822, so this year marks his 200th birthday. We are dedicating a contest in all four issues of insideKWS in 2022 to the “father of modern genetics.” We explain who he was, what he found out and what his discoveries mean for us at KWS.
Mendel’s laws are familiar to all of us from biology classes. In 1856, the Augustinian monk Gregor Mendel observed red- and white-flowered plants during his crossbreeding experiments. He realized that two “heredity factors” (which we now call genes) must exist for each trait, but that only one is passed on. The dominant trait, in this case the red flower color, is expressed and not the white flower color.
Mendel’s first law is therefore: If two individuals are crossed with each other and they differ in a trait for which they are both homozygous, then the progeny of the first generation (filial generation F1) is uniform, i.e. identical with respect to the trait under investigation. This Law of Equal Segregation applies both to the external appearance (phenotype) and to the genes (genotype), which are heterozygous in all individuals of the F1 generation. |
