Trisomy X females have an additional X chromosome and are also referred to as metafemales (XXX)

Some articles refer to a 4rth chromosome, but in general the ones that have excess of X chromosomes they are called metafemales.

If a cell ordinarily has 8 chromosomes how many will it have during mitosis and how many will its daughter cells have after mitosis?

If the cell has 8 chromosomes, it should have 8 at the very beginning of mitosis. However during the interphase, specifically the S phase, the chromosomes are duplicated which means that for most of the cell cycle, the cell has 16 chromosomes. However after the cells splits, each daughter cells is left with 8 chromosomes, which is identical to the number of chromosomes in the original parent cell. Hope this helps!


What is happens during the s phase of the cell cycle?

DNA is replicated.


How many chromatids will line up at the equator of the cell during mitosis?

During mitosis, two sister chromatids from each chromosome will line up at the equator of the cell. This occurs after the chromosomes have replicated during the S phase of the cell cycle.


Chromatin or chromosomes are duplicated during g2 phase s phase prophase or g1 phase?

DNA is duplicated in s(ynthesis)-phase, and chromatin structure begins to tighten post-replication and on through G2, if there even is a G2 in whatever particular cell you're looking at (G2 is not a necessary part of the cell cycle and is left out in many different scenarios). Chromosomes (the most compact chromatin structure) begin to condense further during prophase of mitosis with the help of some of the condensin and cohesin complexes.So I would say the answer to your question as written is S-phase.
