Document Summary
I: the passage of genetic information is critical to the reproduction of cells, the physical mechanism of inheritance depends on the behavior of chromosomes. Chapter 13: genes, the physical location of a gene on the chromosome is called its locus (pl. Each are segments of dna representing discrete units of hereditary information chromosome contains a sequence of several hundred to a few thousand genes: the fidelity or the precision of dna replication is important to heredity. A: a single parent cell or organism gives rise to identical offspring e. g. , mitotic division of a mother cell gives rise to two daughter cells or multicellular hydra produces identical offspring by budding. Except for mutations, which are rare events, the offspring are identical to the parent. In other words, the offspring of asexual reproduction are clones (identical copies) of their parents. B: results in greater variation in genetic material (cid:0) offspring vary in genetic composition from parents and siblings.
