How can you use “polytene” in a sentence? Here are some example sentences to help you improve your vocabulary:

Rather, it is possible that this phenomenon indicates allelic-interactions, particularly given that the alleles are closely associated in a polytene chromosome at the time they are processed (homologs are paired in the polytene anlage of Stichotrichs [ 60 61 ] ). For instance, transvection is a phenomenon dependent on homolog pairing; transvection normally is evidenced by rescued gene expression in heterozygotes of two alleles defective in different cis -acting sequence features, which interact (in trans ) to essentially complement one another (review: [ 62 ] ).
The second use of polytene chromosomes in evolutionary studies is as tracers of phylogeny [ 3 4 5 6 7 ] . This approach has resulted in important and detailed chromosomal phylogenies for several groups of flies in the genus Drosophila . Lists of species for which polytene chromosome maps have been produced are available [ 8 9 ] , and over 300 species of Drosophila have been examined at this level.
The heterochromatin is either severely under-represented or poorly banded in polytene chromosomes, and aggregates into an unbanded structure known as the chromocenter [ 23, 24].
Polytene chromosomes, which are so valuable in mapping euchromatic genes in Drosophila , provide minimal resolution in the heterochromatin.
We proposed that this nested set is generated by alternative breakage patterns of polytene chromatids of the 81 locus DNA ( [ 27 ] ; bottom, Fig.
