Document Summary

The transmission of one generation to the next is called inheritance, or heredity: genetics- the scientific study of heredity and hereditary variation. Offspring acquire genes from parents by inheriting chromosomes. Parents endow their offspring with coded information in the form of hereditary units called genes. Reproductive cells called gametes are the vehicles that transmit genes from one generation to the next. A gene"s specific location along the length of a chromosome is. Comparison of asexual and sexual reproduction called the gene"s locus. Fertilization and meiosis alternate in sexual life cycles. A life cycle is the generation-to-generation sequence of stages in the reproductive history of an organism, from conception to production of its own offspring. The other chromosomes that are not sex chromosomes are called autosomes. Any cell with two chromosome sets is called a diploid cell and has a diploid number of chromosomes, abbreviated 2n: for humans, the diploid number is 46 (2n=46)
