Show transcribed image text During meiosis, a single diploid cell can produce four haploid cells. Homologous chromosomes form pairs and line up on the metaphase plate during both meiosis and mitosis. Chemotherapy has severe side effects because it not only attacks dividing cancer cells but it also attacks healthy dividing cells. The two sister chromatids of a replicated chromosome are held together by a centromere. Henrietta Lacks donated her "immortal" cancer cells to be used for scientific research. According to Mendelian genetics, phenotype is the physical expression of a gene. Chromosomes line up at the middle of the cell during the phase of cell division called telophase. If an animal has a karyotype of 18 chromsomes, each of its gametes would have 9 chromosomes. At the completion of mitosis, the nucleus of a human somatic cell has 23 chromosomes. The range of human eye color is determined by more than one gene. Independent assortment of chromosomes is the only way in which genetic diversity can be created. Most cancers are caused by inherited gene mutations. Linked genes perform similar functions but are located on different chromosomes. Among humans, only males have a Y chromosome. Incomplete dominance is when one gene inhibits the expression of another gene, such as a Labrador retriever having the gene for brown hair color, but no gene to make pigment. The CRISPR technology uses bacterial plasmids to clone mammals. A homozygous dominant individual can be a carrier for a recessively inherited disorder. A tumor that metastasizes is considered malignant. All 46 human chromosomes are autosomes. Up to 75% of foods found in U. S. grocery stores may contain ingredients from genetically engineered organisms.
