HISTORY OF GENE MAPPING
Since the mid-1970s when scientists obtained the understanding of isolating and interpreting gene or DNA sequences, the idea of mapping a genome became a reality.In addition to the human genome, scientists from around the world have been working on other genomes as well. Genomes from cattle, yeast, mice, and fruit flies are just a few of examples. One map that is currently being worked on is the pig map.
One map of the pig genome is being developed in part here at Iowa State University in collaboration with scientists worldwide. Scientists are utilizing new technologies to produce a map that will show gene locations on the chromosomes. Each pig cell contains 18 chromosomes, plus either two X chromosomes or an X and Y chromosome. So, it will take some considerable amount of time to find all the useful genes. Some of the genes being located determine pig litter size, average daily gain, backfat, loin eye area, and feed efficiency.
The maps you will be looking at come from the PIGMAP project, which was developed by a team of scientists worldwide including those at Iowa State University. The reason for this project is ultimately to help the producer produce hogs with outstanding genetics that will be more profitable for the producer and of higher consistent quality for the consumer.
