Document Summary
Microevolution: small changes in biological evolution, such as a population"s gene pool over a succession of generations. An understanding of inheritance allows know exactly what is going on at the genetic level. There are two types of cells: eukaryotic and prokaryotic. >eukaryotic cells contain a nucleus whereas a prokaryotic cell does not. >nucleus: part of a eukaryotic cell containing genetic material. >w/in a nucleus is chromosomes which are double-stranded dna molecule in nucleus of eukaryotic cells that carries genes and functions in the transmission of hereditary information. Each eukaryotic cell can duplicate itself in a process known as mitosis which is a cellular division resulting in two identical daughter cells w the same number of chromosomes as the parent cell. Important to inheritance and evolutionary processes: meiosis is a process in which cellular division results in the formation of haploid cells that determine an organism"s sex (sex cells or gamete-sperm or egg)
