diploid | cells that have pairs of chromosomes |
homologous chromosomes | pairs of chromosomes that have genes for the same traits arranged in the same order |
haploid | cells that have only one chromosome from each pair |
meiosis | one diploid cell divides and makes four haploid sex cells |
asexual reproduction | one parent organism produces offspring without meiosis or fertilization |
fission | cell division in prokaryotes that forms two genetically identical cells |
budding | a new organism grows by mitosis and cell division on the body of its parent |
regeneration | this occurs when an offspring grows from a piece of its parent |
vegetative reproduction | a form of asexual reproduction in which offspring grow from a part of a parent plant |
cloning p.1 | a type of asexual reproduction performed in a laboratory that produces identical individuals from a cell or from a cluster of cells taken from a multicellular organism |
