Explain how to use a Punnett square to determine the probability of inheriting traits. A Punnett square is a graphical representation that uses the traits of the parents to predict the probability of the possible traits-and genes of their offspring. It allows the traits from each parent to be combined in - format to show all the and possibilities the offspring may inherit.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
