1 gametes reproductive cells 2 nucleotides basic units of DNA molecule; composed of a sugar, phosphate unit, and one of 4 DNA bases. 3 enzymes specialized proteins that initiate and direct chemical reactions in the body 4 hemoglobin protein molecule that occurs in red blood cells and binds to oxygen molecules 5 regulatory genes genes that code for the production of proteins that can bind to DNA and modify the actions of genes 6 homeobox (Hox) genes ancient family of regulatory genes, direct segmentation and patterning of overall body plan during embryonic development 7 autosomes all chromosomes except the sex chromosomes 8 mitosis simple cell division 9 meiosis cell division in specialized cells in ovaries and testes. involves two divisions and results in four daughter cells 10 principle of segregation genes occur in pairs. during gamete production, the members of each gene pair separate, so that each gamete contains one member of each pair. during fertilization the full number is restored and members of gene pairs are reunited 11 locus the position on a chromosome where a given gene occurs 12 alleles alternate forms of a gene 13 homozygous

having the same allele at the same locus on both members of a chromosome pair (TT) 14 heterozygous having different alleles at the same locus on members of a chromosome pair (Tt) 15 genotype genetic makeup of an individual 16 phenotype observable/detectable characteristics of an organism 17 Mendelian traits characteristics that are influenced by alleles at only one genetic locus. ex: blood types such as ABO, sickle-cell anemia 18 antigens large molecules found on the surface of cells
