chromatin
if a cell has 64 chromosomes together, all the offspring cells will have 64 chromosomes each.
They show chromosomes at the point when cell division is about to occur because the chromosomes are condensed and aligned which makes it easy to tell if there are the correct number and configurations of the chromosomes.
Chromosomes
Chromosomes are composed of DNA, which is a molecule that carries genetic information, and proteins that help package and organize the DNA into a compact structure. DNA wraps around proteins called histones, forming a structure known as chromatin, which further condenses into chromosomes during cell division.
Chromosomes are found in the nucleus of the cell and are rod shaped
In mitotic division, chromosomes are arranged individually in the middle of the cell at metaphase, whereas in the first division of meiosis, homologous chromosomes are paired together in the middle. This pairing of homologous chromosomes is known as synapsis and is unique to meiosis.

64 chromosomes
It is a division that reduces the number of chromosomes to half of their number before the division.
They show chromosomes at the point when cell division is about to occur because the chromosomes are condensed and aligned which makes it easy to tell if there are the correct number and configurations of the chromosomes.
Meiosis causes the chromosomes to separate and reduce their number in half during cell division.
The term for when chromosomes fail to separate during cell division is called nondisjunction.
The number of chromosomes in daughter cells formed by the first division is the same as the parent cell, typically 46 chromosomes in humans. This is because during the first division, chromosomes are replicated and then distributed equally between the daughter cells.
