Poultry Genetic Resources and Conservation Biology

Recent generations of poultry students and poultry specialists generally seem to lack awareness of the vast genetic diversity which has accumulated in the domestic birds. This diversity has tended to become segregated within the realms of special purpose and special group such as industrial breeders and producers. There are many variants and variation in relation to species, body systems, and p...

Animal genetic resources conservation in the Netherlands and Europe: poultry perspective.

Increased global use of highly productive breeds of farm animals has been coupled to loss of genetic diversity in most species. In European countries, various governmental, non-governmental, and private organizations try to preserve genetic diversity of livestock in situ (e.g., by stimulating the use of indigenous, rare breeds by farmers; in nature reserves; or in noncommercial farms). In the c...

Collecting pollen for genetic resources conservation 25

Pollen grains are the mature male (haploid) gametophyte of higher plants. These tiny organs (10-100 IJ.m in diameter) develop in the anthers (Stanley and Linskens, 1974). When the flower opens the anthers become exposed to the environment and dehydration triggers a mechanism for release of the pollen. In the process, the pollen also dehydrates. Though the pollen of most species can withstand dr...
