How many chromosomes in maize

The ear or maize carries generally 8 to 24 rows of kernels whereas teosinte has only two rows. The teosinte ear is fragile the maize ear is not. The seed as is commonly named is really a karyopse caryopse , a single-seed fruit kernel. Teosinte can be crossed readily with maize and the offspring is fertile whereas Tripsacum is more or less strongly isolated sexually and their hybrids are not fully fertile. Teosinte genes display the same chromosomal and gene arrangements as maize in contrast to Tripsacum that is more dissimilar.

Introduction Maize is among the most extensively studied plant species in the history of genetics. General Characteristics of the Maize Genome The maize genome is genetically diploid and consists of 10 chromosomes with an estimate size ranging from 2. Intraspecific Diversity of Maize Early cytogenetic studies showed considerable line-specific differences in heterochromatin, or C, banding, and heterochromatic knob distribution.

Duplication and Polyploidization Like in other cereals and plants in general, polyploidization has played an important role in the evolution of the maize genome [ 73 , 74 ]. Table 1. Distribution and proportion of features in the annotated genomes of 4 grasses. Table shows a comparison of major genomic element types between 4 published references. References E. Bennetzen and S.
