Mitosis and meiosis concept map. Paul andersen explains how the cell cycle is used to create new cells. Paul andersen describes mechanisms that increase the genetic variation within a population. It has been designed for biology students at the college and high school level. 038 signal transduction pathwaysmov paul andersen explains how signal transduction pathways are used by cells to convert chemical messages to cellular action.
Some genes in two copies are lethal to the organism. This biocoach activity will help you review meiosis the two successive divisions of a diploid cell of a sexually reproducing organism that result in four haploid progeny cells each with half the genetic material of the original cell. A dominant gene shortens the spine and is the cause for no tail. Mitosis is the process that a somatic cell divides into two daughter cells.
The biology project is fun richly illustrated and tested on 1000s of students. The creation of identical diploid daughter cells through mitosis is described. The manx breed of cats is known for being tailless though some are born with tails. Sockosome models of chromosomes made from pairs of socks are used to illustrate the principles of mitosis meiosis and fertilization or with teacher preparation notes or.
The biology project an interactive online resource for learning biology developed at the university of arizona. He begins by discussing how horizontal transfer can move genetic material between bacteria. Drag the labels from the left to their correct locations in the concept map on the right.
