Paragraph 1:
Gregor Mendel was the first person to make precise
observations about the biological
mechanism of inheritance. This happened a little over 100
years ago in Austria, where Mendel spent
his leisure hours performing experiments with pea plants of
different types. He crossed them
carefully and Look notes about the appearance of various traits,
or characteristics, in succeeding
generations. From his observations, Mendel formed a set of 2
rules, now known as the Mendelian
Laws of Inheritance, which were found to apply not only to
plants but to animals and human beings
as well. This was the beginning of the modern science of
genetics.
