The rainbow baby is the name given to a duck whose life span is shorter than a human, but whose genes are passed on in the baby’s genes.
Rainbow babies are often the result of crossbreeding, where the father and daughter have identical genetic material, but with one difference.
A rainbow baby has a “doubled number” of genetic markers.
This means that the mother is half of a rainbow baby and half of an ordinary duck.
“I would say that the baby is a rainbow duck, but you don’t really know how a rainbow comes about,” says Sarah Wilson, a geneticist at University College London, UK.
The two-year-old duck was born in February and her first test results are due out in October.
Wilson, who was not involved in the research, says the results will help scientists better understand the origins of the baby duck and other rainbow duck species.
“We are not sure why it is so different to other ducks, but it does have some of the same features that make it special,” she says.
“For example, the two-thirds of the genes in the duck are shared between the father [and] the daughter.
This is the kind of genetic inheritance that has been reported in many other species, but this is unique.”
A rainbow duck’s genealogy In the past, researchers have suggested that the two different genetic signatures found in rainbow ducks might have arisen through interbreeding.
But Wilson says the new study has shown that the duck’s origins are much more complex.
“These two different types of inheritance, the mother-to-daughter [and the father-to/son] type, are all very different, so the genes that have a triplet on one chromosome, on the other, could have come from different parents,” she explains.
The researchers found that the rainbow ducks have three different types: a triple-chromosome gene, which is inherited from both parents, and a “two-chromochromosome” gene, a double-chromocome gene. “
But we have shown that in the rainbow duck that they have both two types of gene inheritance.”
The researchers found that the rainbow ducks have three different types: a triple-chromosome gene, which is inherited from both parents, and a “two-chromochromosome” gene, a double-chromocome gene.
Wilson says that if there were more parents involved in creating the baby, it would have “more of these three different gene types”.
“You would have a mix of the three different versions of the gene,” she said.
The gene on either side of the triple- or two-chromo-dominant gene is called a “triad” and can give a duck the ability to fly. “
And it would be different on the mother and the father’s side, but also different on both sides.”
The gene on either side of the triple- or two-chromo-dominant gene is called a “triad” and can give a duck the ability to fly.
“This means that if you put a triple, you have an extra pair of chromosomes on the side that’s also a tetra, which means that they can carry more genes on each side, which gives them a different flying ability,” Wilson says.
A geneticist and biologist at the University of California, Davis, Dr Mark Niehaus says that rainbow ducks are “probably the best-studied species in the world”.
The duck, which lives in the Australian desert, is one of the few known species that have three genes. “
It is very exciting that they are also very rare.”
The duck, which lives in the Australian desert, is one of the few known species that have three genes.
The scientists have identified genes for an ability to breathe, which allows them to breathe in water, and two genes for “biofilm” – which allows the duck to make its own protective mucus that acts as a filter on the air.
The team says the duck may be able to adapt to desert conditions and thrive in the warmer parts of the world.
But there is one key issue the researchers are still working on: how does the duck control its heat?
Dr Nieau says that there is no definitive answer.
“There are many questions,” he says.
“We have done some research on ducks that have been frozen for years, but the temperatures are really high, so it is difficult to really test them to see if they are adapting to them.”
If they are, we might have some insights into what the ducks are doing at the temperature and the environment, but we are not really sure.
