Document Summary
Normally self-ferilize: pollen grains from stamen land on carpel of same lower. Experimental cross pollinaion: remove anthers before mature pollen produced prevent self-ferilizaion, transfer pollen from diferent lower to carpel, results in irst generaion f1. Character: a heritable feature that varies among individuals. Mendel selected 7 pairs of characters ( varieies of peas) He quaniied his indings (not merely described: used experimental approach, planned experiments, recorded data, mathemaical analysis of results, first to apply quanitaive methods in study of inheritance. True-breeding: plants that produce the same variety of ofspring when they self-pollinate generaion ater generaion. All individuals of line have same characterisics: all express same phenotype, appearance or characterisics of an organism, physical or chemical expression of an organism"s genes. Sperm and egg contain sampling of luids from various parts of body. During reproducion, luids blend to form intermediate ofspring. F1 = irst ilial generaion (ilial lain for son ) Trait that disappeared in f2 reappeared in f2.
