Document Summary
Gregor mendel used garden peas to study patterns of inheritance and discovered the fundamental rules that govern inheritance. 10. 1 the beginning of genetics: mendel"s garden peas. General public and scientists believed in the blending theory of inheritance: hereditary traits blend evenly in offspring through mixing of parents" blood. Mendel studied a variety of heritable characteristics (also known as characters) A variation in a character is known as trait. Established characters are passed on in the form of discrete hereditary factors, now known as genes. Mendel observed the result of segregation of chromosomes (genes located to gamete in meiosis: parental traits appear unchanged in offspring, traits disappeared in one generation to reappear unchanged in the next generation. Mendel"s most important innovation was his quantitative approach to science. 10. 1a mendel chose true-breeding garden peas for his experiments. Male gametes are sperm nuclei contained in the pollen; produced in the anthers of flowers.
