It is important to include what the following is for a person to know the correct answer. With this information missing a person will not know what appearance of the chromatids is.
It actally spelt prophase...1. The first stage of mitosis, during which the chromosomes condense and become visible, the nuclear membrane breaks down, and the spindle apparatus forms at opposite poles of the cell.2. The first stage of meiosis, constituted by a series of events that include the thickening and coiling of the chromosomes, synapsis of homologous chromosomes, tetrad formation, and crossing over.
In the first stage, called interphase, the cell grows and copies its organelles and chromosomes. After each chromosomes is duplicated, the two copies are called chromatids.
Your question is not really clear, but male and female sex cells are called "gametes".
A karyotype is the characteristic chrosome complement of a eukaryotic species. The preparation and study of karyotypes is part of cytogenetics. In normal diploid organisms, autosomal chromosomes are present in two identical copies. There may, or may not, be sex chrosome. Polyploid cells have multiple copies of chromosomes and haploid cells have single copies. The study of whole sets of chromosomes is sometimes known as karyology. The chromosomes are depicted (by rearranging a microphotograph) in a standard format known as a karyogram or idiogram: in pairs, ordered by size and position of centromere for chromosomes of the same size. The study of karyotypes is made possible by staining: usually a suitable dye is applied after cells have been arrested during cell division by a solution of colchicine Sometimes observations may be made on non-dividing (interphase) cells. The sex of an unborn foetus can be determined by observation of interphase cells.

It actally spelt prophase...1. The first stage of mitosis, during which the chromosomes condense and become visible, the nuclear membrane breaks down, and the spindle apparatus forms at opposite poles of the cell.2. The first stage of meiosis, constituted by a series of events that include the thickening and coiling of the chromosomes, synapsis of homologous chromosomes, tetrad formation, and crossing over.
haploids and diaploids
If it's going under Mitosis here's how: 1) Prophase: The chromosomes appears. Nuclear Membrane disappears. The centrioles appears. 2) Metaphase: The spindle fibers attaches to chromosomes and the chromosomes make a line in the equator of the cell. 3) Anaphase: The spindle fibers pull the chromosomes appart, separating the two chromatids. 4) Telophase: The nuclear membranes starts to appears and the chromosomes again froms chromatins. Cytokinesis starts. Some Extra Information For You to Understand: Centrioles: The organelles that goes to the sides of the cell and pull the chromosomes apart. Equator: The middle of the cell. Spindle Fibers: The fibers of the centrioles. Chromosomes: The structure that is formed of two chromatids attached by a centromere. Chromatin: The form of chromatids when they are long a untidy in the nuclear membrane. Cytokinesis: The separation of cytoplasm in to two. Also You Should Know: A) Before mitosis, there is a phase called Interphase. In interphase the (think after cytokinesis) the cell storages food grows and lastly duplicates it chromatin number so both cells can have the same number of chromosomes with the parent cell. B) In mitosis "Parent and Daughter Cells" are identical.
sperm and egg
Yes. Chromosomes are DNA that have been wound around histones to form nucleosomes. The nucleosomes that have condensed are what forms the complete chromosomes.
Other sections include plants, animal systems, invertebrates, vertebrates, and ... Chromosomes are the things that make organisms what they are.
Telomere - The ends of the chromosome. Centromere - The primary constriction of the chromosome. Chromatid - A single molecule of DNA. The centromere also divides the chromosome into a short arm (p) and a long arm (q).
Fruits on animal crossing include: pears, peaches, apples, oranges, cherries, and coconuts.
The introduction should include a description of the species in the environment in which the experiment is being conducted.
Some of the past key rates for world market indices would include the DOW crossing 10,000, the Nikkei crossing 10,000, the S&P crossing 1000 and the TSE crossing 10,000.
