Document Summary
Q2: the constricted (pinched-in) region of a eukaryotic chromosome is called a. According to the darwin theory of evolution, a population could pass on genetics to allow. Sperm and eggs for a new individual to be generated. The widely accepted hypothesis at the time was that the genetic information were blended at fertilization. Charles darwin had problems with the blended hypothesis. Uniform populations (no variation) could not be accepted into selected pressure. Flower colour, round or wrinkled peas, pod colour. True breeding varieties (ie a particular trait was consistently inherited from one generation to the next) Cross fertilize (cross mate) and self fertilize (self mate) different varieties of the peas. F1 generation was no blending, only purple flowers. F2 offspring projected a trait that was supressed in the f1 generation. Only the purple flower was affecting flower colour in the f1 hybrids. He called the purple flower colour the dominant trait and the white flower colour the recessive trait.
