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

Although banding in the proximal regions of the polytene chromosomes is not as distinct as in the euchromatic regions, comparison of the two datasets shows the approximate extent of overlap between the mitotic and polytene cytogenetic maps (Table 1).
The ploidy can reach ~64 in some Spirotrichs [ 21 22 ] . Thus, each sequence that survives subsequent elimination (MAC-destined) is represented by numerous polytene chromatids; in principle, each could be processed differently.
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].
Not all identical polytene chromatids of the anlage are processed identically, as evidenced by the generation of alternative processing families of MAC chromosomes.
