chromatid – Flashcards

each half of a duplicated chromosome

Together, the two chromatids which refer to the duplicated chromosomes that remain attached (by the centromere). Homologous chromosomes are divided in meiosis I. Sister chromatids are not divided until meiosis II.

are very similar to each other, since they have the same length and carry the same genes, but they are not copies of each other.

is a process in cell division during which the number of chromosomes decreases to half the original number by two divisions of the nucleus. Meiosis results in the production of sex cells.

is the production of gametes.

cells with little more than DNA that are eventually broken down.

is the failure of homologous chromosomes or sister chromatids to separate during meiosis.
