Dog Genome Mapped, Shows Similarities to Humans

Researchers have finished mapping the genome of the domestic dog.
[1] The results show among other things that dogs, mice, and
humans share a core set of DNA.
A rough sequencing of a poodle's genome was reported in
2003, but it covered only about 75 percent of the genes.
[5] This time, "we have sequenced 99 percent of the genome
of a female boxer," said Kerstin Lindblad-Toh, a geneticist
at the Broad Institute of Harvard University and MIT in
Cambridge, Massachusetts. She is the lead author of the
dog-gene study, which appears tomorrow in the journal
[10] Nature.
The researchers also examined DNA from ten different dog
breeds to spot genetic differences between them.
The comparison could help scientists find the genetic roots
of dog behavior and physiology and − perhaps most
[15] importantly − help them identify genes that cause diseases
in both dogs and humans.
