Question

GENETICS
Many attempts have been made throughout history to explain the similarity between parents and children.
People thought, for instance, that the substances responsible for heredity came from the blood of both parents and were mixed together in the child. This idea can be found in expressions like “royal blood” or “bloodline”. Another theory suggested the existence of a miniature copy of the father in his productive cells. But we know, today, that heredity is carried by the genes, which are chromosome sectors transmitted from parents to children.
The basic laws of heredity are studied by genetics. These laws were stated by Augustinian monk Gregor Jonathan Mendel (1822-1884) in a monastery in the city of Brünn, Austria (now a Czech territory).
Mendel used peas in his experiments because they could be easily observed. He cross-pollinated round peas with wrinkled peas. As a result, two thirds of the peas had pods containing both round and wrinkled peas. Mendel’s experiment demonstrated that the gametes (ovule and pollen grain in plants, egg cells and spermatozoa in animals) contain some factors (genes) That are responsible for the appearance of characters in the organism. When Fertilization occurs, the genes carried by the male are combined with those carried by the female. The new plant inherits half of its genes from each parent.
