Statement A: Mendel’s focus on single difference between pea strains and similarities with respect to other traits to other characters allowed him to study the inheritance of one pair of traits of a character at a time.
Statement B: The results of Mendel’s experiments went unappreciated until the turn of the 19th century.
Mendel’s focus on singular differences between pea strains allowed him to study the inheritance of one trait at a time. Other biologists had attempted to follow the inheritance of many traits simultaneously, but because the results of such experiments were complex, they were unable to discover any fundamental principles about heredity.
The results of Mendel’s experiments went unappreciated until the turn of the century, well after his death. However, once Mendel’s publications were rediscovered by geneticists investigating the function and behaviour of chromosomes, the implications of his postulates were immediately apparent.
