Chromosomes are DNA molecule that is packaged in the nucleus of each cell with the appearance of a thread like structure. Chromatids represent one of two identical halves of replicated chromosomes in human beings. Chromosomes are separated into either a short arm (p) or a long arm (q), and the constricted region responsible for this separation is known as a centromere. Any of a human's numbered chromosomes that aren't sex chromosomes are considered autosomes. Sex determination is decided by a sex chromosome, which is any type of chromosome participating in sex determination. Heredity is predicated upon physical and functional determination, which is the definition of a gene. Karyotype tests are able to produce an image of an individual's collection of chromosomes. The definition of a phenotype is representative of a person's observable traits including height, eye color, and blood type. The definition of a human being's genotype is that this represents the person's collection of genes. Whenever two or more versions of a gene is present, this is an allele. ...
