Document Summary

The features/characteristics of the organism are dictated primarily by genes inherited from the parents. Mendel worked on the basic concepts of inheritance patterns. Concept that inherited traits mixed to create a composite characteristic in offspring. Ex: purple & white flowers producing a blend in their offspring. Offspring are a blend of traits from both parents. Gregor mendel: famous for the crossing with pea plant varieties, developed the basic ideas of genetics long before chromosomes & genes were discovered a. Pea plant experiment (7 genes x 2 pairs of chromosomes = 14 chromosomes) Transferred pollen from stamens of white flower to carpel of purple flower. Examined offspring; all purple flowers: mendel"s first law: segregation of alternate factors - basically summarizes meiosis. The purpose of this experiment was to prove the blending inheritance theory i. ii. iii. i. ii. iii. iv. i.
