Recombination makes a substantial contribution into generation of genetic variability. It mediates homologous chromosome paring and segregation at meiosis [1]. Studies on various species by various methods demonstrated non-random distribution of recombination sites along the chromosomes. Mammalian chromosomes ...

Genomic organization of alpha satellite DNA on human chromosome 7: evidence for two distinct alphoid domains on a single chromosome. A complete understanding of chromosomal disjunction during mitosis and meiosis in complex genomes such as the human genome awaits detailed characterization of both the mole...
Term/Concept: Haploid/Meiosis i. In humans, the haploid number, n equals: a) 2n. b) 44. c) 23. d) 46. Term/Concept: Nondisjunction/Meiosis ii. Trisomy is a consequence of ___, the unequal distribution of chromosomes during meiosis. a) recombination b) cytokinesis c...
The term, germ granules, encompasses a class of non-membrane bounded organelles found in the specialized germ cells that generate sexual cells upon meiosis in the developing embryo and are referred to as P-granules, germinal bodies or Nuage bodies, depending on the organism of origin (reviewed ...
Segmental duplications (SDs) are not evenly distributed along chromosomes. The reasons for this biased susceptibility to SD insertion are poorly understood. Accumulation of SDs is associated with increased genomic instability, which can lead to structura
Autosomes show gradation in size, X is of medium size while Y is the smallest element. Both X and Y are positively heteropycnotic in diffused stage but become isopycnotic in diplotene/diakinesis stage and divide equationally during meiosis I, At metaphase II, X and Y get associated, the...
