Pairing occurs during the prophase of meiosis I, after the chromosomes have been duplicated. Centromere mention as 1, 2, 3 and 4

Which of the following is correct statement Types of disjunction in a translocation heterozygote during meiosis I.

A) Centromeres 1 and 3 go to one pole and centromeres 2 and 4 go to the other pole, producing non fuctional gametes.

B) Centromeres 1 and 2 go to one pole and centromeres 3 and 4 go to the other pole, producing viable gametes.

C) Centromeres 2 and 3 go to one pole and centromeres 1 and 4 go to the other pole, producing euploid gametes.

D) Centromeres 2 and 3 go to one pole and centromeres 1 and 4 go to the other pole, producing non viable gamete

Following statements are regarding to the centrosome cycle of an animal cell.

A. During G1, the daughter procentrioles continue to elongate.

B. During S phase, daughter procentrioles form adjacent to maternal centrioles so that two pairs of centrioles become visible within the centrosome. 

C. During G2 phase, the centrosome contains a single pair of centrioles.

D. At the beginning of mitosis, the centrosome splits, with each pair of centrioles becoming part of its own centrosome. As they separate, the centrosomes organize the microtubule fibres that make up the mitotic spindle.
