Are humans more closed to mouse or chicken?
Explain.
Answers
Answer:
It turns out that the overall pattern of gene order in the human genome is similar to that of the chicken, harking back to our reptilian common ancestor more than 300 million years ago. ... Mice, like all rodents, breed much more quickly and frequently than humans, giving mutation much more scope to act.
About 60 percent of chicken genes correspond to a similar human gene. However, researchers uncovered more small sequence differences between corresponding pairs of chicken and human genes, which are 75 percent identical on average, than between rodent and human gene pairs, which are 88 percent identical on average.
When it comes to protein-encoding genes, mice are 85 per cent similar to humans. For non-coding genes, it is only about 50 per cent. The National Human Genome Research Institute attributes this similarity to a shared ancestor about 80 million years ago.
