Example sentences for: mauritiana
How can you use “mauritiana” in a sentence? Here are some example sentences to help you improve your vocabulary:
The expected number of polymorphisms between D. melanogaster and D. mauritiana was calculated based on the Drosophila neutral substitution rate of .016 (± 0.005) substitutions per site/million years [ 18 ] on 685 bp over a divergence time of 2.7 million years [ 19 ] .
The sequence of this region in a D. melanogaster (Dimonika, Africa) and D. mauritiana (Mauritius, Africa) strain was aligned with the homologous region in the sequenced D. melanogaster y; cn bw sp strain (Figure 3).
The melanogaster sequences were found to be only 1.3% (9 substitutions/685 nucleotide sites) diverged from that of D. mauritiana . This value is significantly less than half of the expected 4.3 % (± 2.7) divergence based on the Drosophila neutral substitution rate of 0.016 (± 0.005) substitutions/site/million year [ 18 ] over the estimated 2.7 million years separating the two species [ 19 ] .
Thus, to further test the adaptive hypothesis we compared the level of sequence divergence within the LTR and its flanking intronic sequence between the two sibling species Drosophila melanogaster and Drosophila mauritiana . If the LTR-containing intron is under stabilizing selection, a lower than neutral rate of substitution would be expected.
