- In his paper, Mendel reported as "Experiment 1" the following cross
- between such two strains. The ovules of flowers of a strain pro-
- ducing ordinary round seeds were cross-fertilized with pollen from
- flowers of a strain producing unususal, wrinkled seeds, and ovules
- of plants that produced wrinkled seeds were cross-fertilized with
- pollen from plants that produced round seeds. Several hundred
- first-filial-generation hybrid seeds resulted from this cross, all
- of which were round. In the next year, Mendel planted 253 of these
- round hybrid seeds, allowed the resulting pea plants to self-
- fertilize, and obtained 7324 second-filial-generation seeds from
- them. He found that of these seeds 5474 were round and 1850
- wrinkled,giving a ratio of round : wrinkled = 2.96:1
