Submetacentric chromosomes are the chromosomes in which the centromere is placed slightly away from the centre. Discussion and conclusion The sheep chromosomes were first studied by Banding with Giemsa or 5-bromodeoxyuridine (BrdU)-acridine orange allows it to be easily distinguished from chromosomes 6 and 7 that are the closest submetacentric chromosomes in size. Example: Human chromosomes 4 to 12 are submetacentric. In a submetacentric chromosome, the centromere is off center resulting in a shorter “p” and longer “q” arm. Human chromosomes are classified into three types based on the position of the centromere. 1, 2, and 5, and the relative length of the X chromosome. This means that the centromere that usually forms the central point of a chromosome, lies away from the centre, making one arm of the chromosome longer than the other. The X chromosome is one of the two sex-determining chromosomes in many organisms, including mammals (the other is the Y chromosome), and is found in both males and females.It is a part of the XY sex-determination system and X0 sex-determination system.The X chromosome was named for its unique properties by early researchers, which resulted in the naming of its counterpart Y chromosome… Telocentric.

Chromosome pairs form three size groups (pairs 1–2, 3–7, 8). (Cell Biology & Molecular Genetics) Submetacentric chromosomes have their centromere about midway between the telomere and middle of the chromosome as shown. Both arms of metacentric or submetacentric chromosomes are independent to pair and the pairing process is simultaneous in the four chromosomes of each set. Since these two pairs of homologous chromosomes do not undergo crossover, the resulting gametes after meiosis may have four (4) allele combinations. have the centromere slightly offset from the center leading to a slight asymmetry in the length of the two sections. SUBMETACENTRIC Chromosome 18 spans about 78 million DNA building blocks. Submetacentric meaning (cytology, of a chromosome) Having the centromere between one end and the middle, and thus having a long arm, and a short arm. If the chromosome is a submetacentric chromosome (One arm big and the other arm small) then the centromere divides each chromosome into two regions: the smaller one, which is the p region, and the bigger one, the q region. Chromosomes Ia and Ib are homologues and chromosomes IIa and IIb are homologues. 2 submetacentric. Its shape is in the form of L. The submetacentric chromosomes have the centromere slightly deviated from the center, which leads to a slight asymmetry in the length of the two sections. Type of chromosome.
