Sayings by Gregor Mendel
Jesus appeared to the disciples after the resurrection in various forms. He appeared to Mary Magdalene so that they might take him for a gardener. Very ingeniously these manifestation of Jesus is to our minds difficult to penetrate. (He appears) as a gardener. The gardener plants seedlings in prepared soil.
Those traits that pass into hybrid association entirely or almost entirely unchanged, thus themselves representing the traits of the hybrid, are termed dominating and those that become latent in the association, recessive.
My experiments with single traits all lead to the same result: that from the seeds of hybrids, plants are obtained half of which in turn carry the hybrid trait (Aa), the other half, however, receive the parental traits A and a in equal amounts. Thus, on the average, among four plants two have the hybrid trait Aa, one the parental trait A, and the other the parental trait a. Therefore, 2Aa+ A +a or A + 2Aa + a is the empirical simple series for two differing traits.
This circumstance is especially important for the evolutionary history of plants because constant hybrids acquire the status of new species.
Whether they will retain the characteristics of the hybrid, or whether they will show variations, will be determined by next year's observations.
Darwin's statements concerning hybrids of the genera mentioned in The Variation of Animals and Plants Under Domestication, based on reports of others, need to be corrected in many respects.
