deletion-occurs when an end of a chromosome breaks off or when two simultaneous breaks lead to the loss of an internal segment
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.
A broken part of a chromosome that becomes attached to a nonhomologous chromosome without molecular loss is known as a translocation. This can lead to genetic disorders if the translocated segment disrupts the function of important genes located on the chromosome.
The condition in which a diploid cell is missing a chromosome or has an extra chromosome is called aneuploidy.
to complete the meiosis cycle
The chromosome carried only by the sperm is called the Y chromosome, which determines the male gender when combined with the X chromosome from the egg during fertilization.

Quite simply a chromosome map.

S phase is complete when each chromosome has been duplicated.

" gets lost "I think you are describing a nondisjuction event where the chromosomes are not properly pulled apart to their proper positions by the mitotic spindle.
it is called a sister chromosome :)
