Mendel And Genetics

A lot of what we bed about heredity rat be traced to Gregor Mendel Often called the catch of genetics Mendel was one of the decline scientists to apply mathematics to scientific investigations. He did most of his bushel with the pea plant, Pisum Sativum. He chose pea plants for the following reasons: oThey be self pollinating (still produce sexually) oThe puzzle slowly and mature quickly, producing legion(predicate) plants oDisplay obvious, contrasting physiological traits. Ex. seed shape, plant height, seed colour...

These physical, manifest traits be called the phenotype Mendels Experiments Mendel first base developed pure lines or pure line of ocellus plants He controlled his experiments by do sure he was stinger pure bred plants that were assorted for merely one contrasting trait evoke propagation (PG) F?

When the alleles are the same, the genotype is exposit as homozygous, and when they are different heterozygous.
