nuclear division mechanism that forms gametes or spores; basis of sexual reproduction; divides parental chromosome number in half
one of two attached members of a duplicated chromosome
in chromosome the constricted region where microtubules of spindle bind
dynamic network of microtubules that grow from opposite poles of the cell
having two of each type of chromosome characteristic of the species
includes two centrioles; two of them move to opposite poles of nucleus and pull apart sister chromatids
all offspring inherit the name number and kinds of genes from a single parent
involves meiosis; forms mature reproductive cells called gametes; then fertilization
sequences of DNA that encode heritable information about traits
arise by mutation and encode slightly different versions of the same trait
mature reproductive cells formed by meiosis of germ cells
pairing at meiosis and having the same structural features and pattern of genes; same length, shape, and genes
having one of each type of chromosome characteristic of the species
process where chromosome and its homologous partner exchange corresponding segments
