The basic diploid chromosome of maize (Zea mays L.) is comprised of 20 A chromosomes (As).

2D, BT and BST were highly heterochromatic and easily distinguished from A chromosomes with conventional C-banding, as described earlier (Porter and Rayburn, 1990).

B chromosome contains active genes and impacts the transcription of a chromosomes in maize (Zea mays L.

The number of C-bands in the A chromosome set were detected to determine whether the variation of this structure can account for numerical polymorphism for Bs.

In the GZ52 landrace population, 11 C-bands were seen in the A chromosome set, while Bs were not identified.

It appears, therefore, that recombination in the distal wheat segment of MA chromosomes produces a chromosome without breeding value with an approximate frequency of about 0.9%.

Both younger and older women were equally likely to have a chromosome error in the first stage, regardless of their age, the researchers reported last week at a meeting of the American Pediatric Society and Society for Pediatric Research in New Orleans.
