They are long strands of DNA when unraveled are over a meter long.
You have 23 pairs of chromosome as a human. In each pair, you have one from your mother and one from your dad. All of your genes are on these.
This is called diploidy.
you would call it sister chromatids
Diploid is the term for cells that contain two chromosomes of each pair. Euploid is a term meaning normal body cells.
homologous chromosomes- Erick Rosales
Normal body cells, also called diploid cells, contain 46 chromosomes. These are matched up in 23 pairs, one pair being the gender chromosomes.
They both 'perform' highly complex and specific operations on chromosomes. Both start with two pair of chromosomes - one newly synthesized (4N). Mitosis ends with one pair in each of two daughter cells (2N), while Meiosis ends with four gametes each having one chromosome (1N).
HomologousWe receive one complete set of chromosomes from each parent. This means that for each chromosome, say chromosome 7, there are two copies in every cell of our bodies: the maternal and paternal copies of chromosome 7.The two copies of one chromosome are called a pair of homologous chromosomes.

Two chromosomes in a pair that have genes that code for the same traits are called homologous chromosomes. These chromosomes are in the same locations or loci.
Chromosomes are arranged in pairs and they are not yet named, but each of the pair is identified by numbers 1 to 22 (ie., twenty-two pairs of autosomes) and the 23rd pair by xx (in females) or xy (in males) to represent gonosomes (sex chromosomes).
sperm and egg, each have 23.
two chromosomes that have the same length and same apperence.
Because in the events of Meiosis the chromosomes split and then the sex cell only has half the number of chromosomes. Once the sperm & egg unite (fertilization) then the chromosomes pair up, and you get all 46 chromosomes.
2 cells and twenty chromatids each (or twenty half-chromosomes each), but I'm not sure for the human sex cells (meiosis) if they are the same for all the other cells in the body (mitosis). If eukaryotic cell having 20 chromosomes undergoes meiosis four cells will be formed, each having 10 chromosomes. This happens because in meiosis I, pairing between homologous chromosomes takes place and each chromosome from this pair gets separated to the opposite pole resulting into reduction of chromosome by half their original number. From these two haploid cell of meiosis I, meiosis second further divides each of these two cells to two by mitosis. Thus, four cells with 10 chromosomes each are formed.
