Vocabulary Ladder A
Meiosis
A process where one diploid cell divides into four
haploid cells(sex cells)
Haploid
Cells that have only one chromosome from each pair
Diploid
Cells that have pairs of chromosomes (one from each
parent)
Gamete
A male or female sex cell
Homologous Chromosomes that have genes for the same traits
chromosomes arranged in the same order
Sister
Two identical chromatids joined by a centromere
chromatid
Crossover
When homologous pairs of chromosomes exchange
genetic information
Interphase
The stage in the cell cycle when the DNA/organelles
make copies of themselves
Prophase
Chromosomes become visible, nuclear membrane
dissolves, spindle fibers attach to sister chromatids.
(in meiosis, homologous pairs come together and
crossover occurs)
Metaphase
Spindle fibers pull the sister chromatids(mitosis/
metaphase II) or
homologous pairs (meiosis) to the middle of the cell.
Anaphase
Sister chromatids are pulled apart (mitosis)
Homologous pairs are pulled to the opposite sides of the
cell (meiosis I)
Telophase
A nuclear membrane forms around the chromosomes
cytokinesis
The cytoplasm and its contents divide.
Sexual
A type of reproduction where the offspring are
reproduction genetically different than the parents
