Chromosome 2 is one of the twenty-three pairs of chromosomes in humans. People normally have two copies of this chromosome. People normally have two copies of this chromosome. Chromosome 2 is the second-largest human chromosome, spanning more than 242 million base pairs [ 4 ] and representing almost eight percent of the total DNA in human cells .
[1] [2] Karyotyping is the process by which a karyotype is discerned by determining the chromosome complement of an individual, including the number of chromosomes and any abnormalities.

Polysomy of chromosomes 1, 2, 4, 5, and 25 are also frequently involved in canine tumors. [16] Chromosome 1 may contain a gene responsible for tumor development and lead to changes in the karyotype, including fusion of the centromere, or centric fusions. [16] Aneuploidy due to nondisjunction is a common feature in tumor cells. [17]
[2] [3] The majority of Pakistan's languages belong to the Indo-Iranian group of the Indo-European language family. [4] [5] Urdu is the national language and the lingua franca of Pakistan, and while sharing official status with English, it is the preferred and dominant language used for inter-communication between different ethnic groups.
48,XXYY syndrome is a condition related to the X and Y chromosomes (the sex chromosomes). People normally have 46 chromosomes in each cell.Two of the 46 chromosomes, known as X and Y, are called sex chromosomes because they help determine whether a person will develop male or female sex characteristics.

The human sperm cell is haploid, so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell with 46 paired chromosomes. In mammals, sperm is stored in the epididymis and released through the penis in semen during ejaculation. The word sperm is derived from the Greek word σπέρμα, sperma, meaning "seed".
