Millet began to differentiate from rice about 50 million years ago, and there is still obvious collinearity in the genome structure after differentiation. The researchers found that millet chromosomes 2 and 9 were fused from rice chromosomes 7 and 9, 3 and 10 respectively. At the same time, they found that these two fusion events also occurred in Sorghum chromosomes, The researchers speculated that the two chromosome fusion events should have occurred before sorghum differentiated from millet.
ite for the above reasoning?
Chromosomes 3 and 10 are unlikely to separate after fusion
