Japanese researchers have confirmed the second case known to science of a chimpanzee born with trisomy 22, a chromosomal defect similar to that of Down syndrome (or trisomy 21) in humans.
Down Syndrome in Monkeys Class: Mammalia Diet: Omnivorous Research into Down syndrome in monkeys offers a unique window into the genetic and developmental complexities of this condition. Scientists have successfully created monkey models with trisomy 21, the chromosomal abnormality that causes Down syndrome in humans. These primates exhibit behaviors and physiological traits reminiscent of..
