An Australian scientist says studying the kangaroo genome might help scientists modify genes in cows so that they produce highly nutritious milk. Kangaroo milk production is of special interest to some scientists because the animals make three distinct types of milk depending on their embryo’s age. The research is part of the Kangaroo Genome Project, an Australian effort to sequence the marsupial’s entire genome. The research was discussed on Monday at the Human Genome Meeting in Berlin. “In the future and after much debate, this gene could be implanted into a cow to make special types of milk,” said Professor Jenny Graves, a scientist from the Australian National University.
