Individual threads that form chromosomes are chromatin.
The individual threads that form a chromosome are called chromatids, specifically sister chromatids when they are identical copies joined together by a centromere. Each chromatid consists of a long strand of DNA tightly coiled around proteins called histones, which help package the DNA into a compact structure. During cell division, chromatids are separated and distributed to daughter cells, ensuring that each cell receives an identical set of chromosomes.

Threads of condensed DNA refer to the highly ordered and tightly wound structure of DNA molecules that form during cell division. These condensed threads, called chromosomes, allow for the efficient segregation of genetic material into daughter cells. Chromosomes are composed of DNA wrapped around proteins called histones, which help organize and compact the genetic material.
If an individual has the chromosome series XY, that individual would be a male. The Y chromosome is passed down from the father and the X is passed from the mother. The X chromosome contains all hereditary factors while the Y chromosome doesn't contain much genetical information at all, except the fact if Y chromosome is present that individual will be a male. This is all only true for Humans. Dosophilla (fruit flies) have different chromosomal expressions.
In humans, which sex chromosome determines if an offspring is a male or female?

Aneuploid - the individual has an extra copy of one chromosome or is missing a chromosome.

The singular form of chromosomes is chromosome.

The condition in which an individual has three copies of a chromosome is called trisomy. It can result in genetic disorders such as Down syndrome, which is caused by an extra copy of chromosome 21.
The chromosome makeup of an individual organism is called a karyotype. A karyotype is a visual representation of an individual's chromosomes, showing their number and structure. It is usually depicted as a chart or diagram displaying the chromosome pairs in a specific order.
If an individual has the chromosome series XY, that individual would be a male. The Y chromosome is passed down from the father and the X is passed from the mother. The X chromosome contains all hereditary factors while the Y chromosome doesn't contain much genetical information at all, except the fact if Y chromosome is present that individual will be a male. This is all only true for Humans. Dosophilla (fruit flies) have different chromosomal expressions.
A male individual is produced when a sperm carrying a Y chromosome fertilizes an egg carrying an X chromosome.
The female sex chromosome, known as the X chromosome, plays a crucial role in determining the biological sex of an individual. Females typically have two X chromosomes, while males have one X and one Y chromosome. The presence or absence of the Y chromosome determines whether an individual develops as male or female.
During cell division, chromatin condenses to form distinct chromosomes, which are made up of DNA and protein. These chromosomes are then aligned in the center of the cell and separated into two new daughter cells during the process of mitosis.
At metaphase I of meiosis in a male individual, there are 223 (8,388,608) different chromosome alignments possible.
