Poultry Genetics For Small and Backyard Flocks: An Introduction

DNA (short for deoxyribonucleic acid)—The material containing the genetic instructions used in development and function of an organism. DNA is arranged in double helix–shaped strands. Gene—A segment of DNA that carries a blueprint for the function of a cell and, ultimately, a particular characteristic of an organism. Chromosome—A structure containing a complete strand of DNA. Chromosomes functi...

Maize and Biodiversity: The Effects of Transgenic Maize in Mexico

Note: Ten chapters were prepared as background for the work of the Maize Advisory Group and for input to the public symposium, held 11 March 2004, in Oaxaca as part of the CEC Article 13 study on maize and biodiversity. These chapters were later reviewed and revised prior to this release, based on comments received at the symposium and during the subsequent comment period. Responses to reviewer...

The genetics of maize evolution.

Maize and its closest wild relatives, the teosintes, differ strikingly in the morphology of their female inflorescences or ears. Despite their divergent morphologies, several studies indicate that some varieties of teosinte are cytologically indistinguishable from maize and capable of forming fully fertile hybrids with maize. Molecular analyses identified one form of teosinte (Zea mays ssp. par...

The Genetics of Vivipary in Maize.

REMATURE germinating seeds have been observed in various plants, including P lemons, oranges, melons, wheat and rye. However, in none of these is there any good indication that the premature germination is the result of changes in the germ plasm. Only in maize has the genetic control of this phenomenon been clearly demonstrated. Such mutants have been described by MANGELSDORF (1923,1926, and 19...
