Hybrid pea plants were known; segregation of traits could be quantitated. Easily observable traits were available such as flower color, seed color, seed shape, pod color, pod shape, flower position, and plant height. Plants were small; easy to grow in large numbers; short generation time for several crosses per growing season. Peas are normally self-fertilizing, but artificial cross fertilizations are readily done.Pea Plant ExperimentMendel's peas typically had 2 seed shapes: round and wrinkled. Mendel produced this experiment by breeding different types of peas together to see which traits were passed to the offspring. Breeding and tracing traits is known as hybridization.)Pea Plant ExperimentMendel made crosses between true-breeding, self-fertilizing plants; He followed the inheritance of distinctive traits in the offspring and kept quantitative recordsMain TheoryMendel had a theory that was comprised of three basic laws; these laws pertained to traits, characteristics, and heredity.Mendel’s First Law“Sex cells of a plant may contain two different traits, but not both of those traits.”Mendel’s Second LawCharacteristics are inherited independently from another (the basis for recessive and dominant gene composition).Mendel’s Third LawEach inherited characteristic is determined by two hereditary factors (known more recently as genes), one from each parent, which decides whether a gene is dominant or recessive.Definitions Gene: is located in the germ plasm usually on a chromosome.Dominant: being the one of a pair of bodily structures that is the more effective or predominant in action Recessive: producing little or no phenotypic effect when occurring in heterozygous condition with a contrasting alleleConsequential EffectsOpened doors for research on:Down SyndromeKlinefelter SyndromeTurners SyndromeOther InterestsMeteorology Theories of Evolution PhilosophyEcclesiastical historyEcclesiastical archeologyGreekHebrewReferencesBlumberg, Robert.
