AP BIO: Cell Cycle

any other cell than a gamete - has 46 chromosomes in humans (diploid cell)

A display of condensed chromosomes arranged in pairs. Used to screen for abnormal numbers of chromosomes or defective chromosomes associated with certain congenital disorders, such as down syndrome.

The 2 chromosomes composing a pair have the same length, centromere position, and staining pattern; also called homologues. Both chromosomes in a pair carry genes controlling the same inherited characteristics.

X and Y chromosomes - determine an individuals sex

The other chromosomes (not the X and Y sex chromosomes).

22 pairs (in humans)

Any cell with 2 chromosome sets; has a diploid number of chromosomes, abbreviated 2n. (ex. humans=2n=46)

Any cell with 1 chromosome set (gametes=egg and sperm); each has n chromosomes (haploid #). (ex. humans=n=23)

Union of gametes (sperm and ovum), culminating in fusion of their nuclei. Restores the diploid condition, forming a zygote. The diploid zygote develops into an adult (as a result of mitotic cell division).

The egg resulting from fertilization; diploid, as it contains 2 haploid sets of chromosomes bearing genes representing the maternal and paternal family lines.
