Dominant (red) and recessive (white) phenotype look alike in the F1 (first) generation and show a 3:1 ratio in the F2 (second) generation Originally from en:Nupedia, by Magnus Manske 11:18, 10 January 2003 Magnus Manske 432x535 (4,955 bytes) (From [[:en:Nupedia]]) Corrected version uploaded on November 13th, 2007 by User:Dietzel65: Previously, the lines would connect the same two parental genes twice.
context_page_description: Mendelian inheritance is a set of rules about genetic inheritance.
  The basic rules of genetics were first discovered by a monk named Gregor Mendel in the 1850s, and published in 1866. For thousands of years, people had noticed how traits are inherited from parents to their children. However, Mendel's work was different because he did experiments on plants, and designed those experiments very carefully.
  In his experiments, Mendel studied how traits were passed on in pea plants. He started his crosses with plants that bred true, and counted characters that were either/or in nature. He bred large numbers of plants, and expressed his results numerically. He used test crosses to reveal the presence and proportion of recessive characters.
context_section_description: The ratios in the diagrams below are statistical predictions. In a large number of crosses, the numbers of offspring with these features will approximate to the ratios given.
