Chapter 13 Vocabulary heredity variation gene gamete somatic cell asexual vs sexual reproduction autosomes sex chromosomes allele dominant vs recessive diploid vs haploid parental generation. Cell Division (Mitosis). Cell division results in two identical . daughter cells.. The process of cell divisions occurs in three parts:. Interphase . - duplication of chromosomes and preparing the nucleus for division. Part 3. Location of genes. Meiosis. Linkage and mapping. A map of the human Y chromosome. 2. Location of genes. One of the things Mendel didn’t solve was exactly where genes are located in cells. His precise description of how genes behaved, though, helped other scientists determine that . Sexual Life Cycles.
