Before we start genetics lets review the process of what makes us all look different compared to our siblings family and classmates Sexual Reproduction Sexual reproduction creates genetic variability That is why we all look different and you look different from your siblings .

Meiosis and Sexual Reproduction Chapter 6 Sexual Reproduction Sexual Reproduction – reproduction that requires two parents and produces offspring that are genetically different from each other and from either parent. Organisms that reproduce sexually are generally diploid: each cell contains two sets of chromosomes—a maternal chromosome set and a paternal chromosome set—one inherited from each parent. . .

Learning objective This learning material is about the life cycle of a cell and the series of stages by which genetic materials are duplicated and partitioned to produce two daughter cells with the 1 identify the stages of meiosis. Only diploid cells caages of meiosis in a diploid cell where 2N = 6Meiosis involves 2 consecutive cell divisions. Since the DNA is duplicated result is 4 haploid cel
