  5. Timeline • 1851 Enrolls in the University of Vienna • 1856 Begins experiments with genes (Pea Plant Experiment) • 1884 died January 6, in Brno, Austria

  6. Organizations • Member of the Zoologist-botanisher Vernin • Austrian Monk

  7. Pea Plant Experiment • Why Mendel Chose the Pea Plant: • Inbred, true-breeding lines were available. • 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.

  8. Pea Plant Experiment • Mendel'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. 

  9. Pea Plant Experiment • Mendel made crosses between true-breeding, self-fertilizing plants; He followed the inheritance of distinctive traits in the offspring and kept quantitative records

  10. Mendel had a theory that was comprised of three basic laws; these laws pertained to traits, characteristics, and heredity. Main Theory

  11. Mendel’s First Law “Sex cells of a plant may contain two different traits, but not both of those traits.”

  12. Mendel’s Second Law Characteristics are inherited independently from another (the basis for recessive and dominant gene composition).

  13. Mendel’s Third Law Each 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.

  14. 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 allele

  15. Opened doors for research on: Down Syndrome Klinefelter Syndrome Turners Syndrome Consequential Effects
