Sentence examples for molecular markers often from inspiring English sources

from other closely related B. dorsalis species complex flies for which morphological or molecular markers often already exist (such as for B. carambolae).

Radiation in some plant groups has occurred on islands and due to the characteristic rapid pace of phenotypic evolution, standard molecular markers often provide insufficient variation for phylogenetic reconstruction.

Studies using molecular markers, often mitochondrial DNA (mtDNA) sequences, to elucidate phylogenetic relationships among cetacean taxa have just as often created new controversy as resolved standing controversy [ 1- 8].

One way to integrate these data is to build a tool that relies on molecular markers often sequenced, which are shared between the genetic and physical maps and documented at MaizeGDB.

For example, within the spruce genera morphological and molecular markers often give conflicting results and multi-locus nuclear DNA data indicates that incomplete lineage sorting is a major challenge for inferring species trees [ 33].

Also, the abundance of AFLP markers in the pericentromeric heterochromatin of RH Chr-5 has given us the unique opportunity to identify and sequence clones from this relatively unexplored genomic region, in which other types of molecular markers often give very limited coverage for anchoring.

It is difficult to compare the FCT values from the AMOVA directly with studies on other organisms as other molecular markers are often used.

Large-scale progeny tests using molecular markers are often hampered by low germination rates.

Segregation distortion of molecular markers has often been reported in the progeny of crossings of cultivated crops × wild progenitors in maize (Doebley et al., 1990; Doebley and Stec, 1993), rice (Cai and Morishima, 2002), pearl millet (Poncet et al., 2000, 2002) and soybean (Keim et al., 1990 a ; Yamanaka et al., 2001; Watanabe et al., 2004).

However, if we select backcross lines with target genes using molecular markers, linkage drag often occurs in indica/japonica.

Dealing with phylogenetic information recorded in molecular markers is indeed often a major challenge.
