Term
SEX CHROMOSOME
Definition
ARE CHROMOSOMES THAT DETERMINE THE SEX OF AN ORGANISM MAY ALSO CARRY GENES FOR OTHER CHARACTERISTICS
Term
AUTOSOME
Definition
ALL OF THE CHROMOSOMES AND THE 44 REMAINING
Term
HOMOLOGOUS CHROMSOME
Definition
ARE THE SAME SIZE AND SHAPE AND CARRY GENES FOR THE SAME TRAITS
Term
DIPLOID
Definition
CELLS HAVE TWO AUTOSOMES FOR EACH HOMOLOGOUS PAIR
Term
HAPLOID
Definition
ONLY ONE SET OF CHROMOSOMES HAVE HALF THE NUMBER OF CHROMSOMES THAT ARE IN DIPLOID CELLS
Term
MITOSIS
Definition
RESULTS IN THE NEW CELLS WITH GENETIC MATERIAL THAT IS IDENTICAL TO THE GENETIC MATERIAL OF THE ORIGINAL CELL
Term
ASEXAL REPRODUCTION
Definition
IS THE PRODUCTION OF OFFSPRING FROM ONE PARENT
Term
MEIOSIS
Definition
OCCURS DURING THE FOMATION OF GAMETES WHICH ARE HAPLOID REPRODUCTION CELLS
Term
GAMETES
Definition
a mature sexual reproductive cell, as a sperm or egg, that unites with another cell to form a new organism.
Term
INTERPHASE
Definition
the period of the cell cycle during which the nucleus is not undergoing division, typically occurring between mitotic or meiotic divisions. Also called interkinesis. Compare G1 phase, S phase, G2 phase.
Term
prophase
Definition
the first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes.
Term
METAPHASE
Definition
the stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate of the spindle.
Term
ANAPHASE
Definition
he stage in mitosis or meiosis following metaphase in which the daughter chromosomes move away from each other to opposite ends of the cell.
Term
CYTOKINESIS
Definition
the division of the cell cytoplasm that usually follows mitotic or meiotic division of the nucleus.
Term
TELOPHASE
Definition
he final stage of meiosis or mitosis, in which the separated chromosomes reach the opposite poles of the dividing cell and the nuclei of the daughter cells form around the two sets of chromosomes.
Term
CELL PLATE
Definition
in plant cells) a plate that develops at the midpoint between the two groups of chromosomes in a dividing cell and that is involved in forming the wall between the two new daughter cells.
