process in which a single cell or set of cells produces offspring that inherit all their genetic material from one parent.
process in which genetic material from two parents combine and produces offspring that differ genetically from either parent.
combination of DNA and protein molecules, in the form of long, thin fibers, making up the genetic material in the nucleus of a Eukaryotic cell.
one of a pair of identical chromosomes created before a cell divides.
region where two sisters chromatids are joined tightly together.
