Meiosis ensures the transmission of traits from one generation to the next. at the same time, it is a key process that introduces genetic variation into the traits that offspring inherit from their parents. in this tutorial, you will explore the genetic context of meiosis. this diagram shows a diploid nucleus (2n=8) in which chromosome replication has occurred in preparation for mitosis (top) and meiosis (bottom). the nucleus at top right is now in prophase of mitosis; the nucleus at bottom right is now in prophase i of meiosis. in the life cycle of an organism, meiosis is paired with the process of fertilization. understanding the life cycle of an organism is the key to understanding how sexual reproduction ensures the inheritance of traits from both parents and also introduces genetic variation. meiosis creates gametes (eggs and sperm) with only a single chromosome set (haploid or: from parental cells with two chromosome sets (diploid or 2n).

Abody cell has been growing and at synthesis proteins. in the nucleus of this body cell, dna replication is taking place. and a copy of the cells genetic material is copied. which of the following is the best conclusion you can make about the life cycle of this cell ? a) the cell is ready to undergo mitosis. and a chemical signal will send the cell to prophase b)the cell is undergoing meiosis and will cross over the genetic material next c)the cell is in the s phase of interphase and will move next to the g2 phase d) the cell is in the g2 phase of the interphase and is ready to begin diving
