Mendel crossed pea plants that produced round seeds with those that produced wrinkled seeds.  From a total of 7324 F2 seeds, 5474 were round and 1850 were wrinkled.  Using the symbols W and w for genes, (a) symbolize the original P cross;  (b) the gametes; and (c) F1 progeny, (d) Represent cross between two F1 plants (or one selfed); (e) symbolize the gametes; and (f) summarize the expected F2 results under the headings: phenotypes, genotypes, genotypic frequency, and phenotypic ratio

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
