Genetic pollution refers to the hybridization or genetic engineering of species. It is applied mainly in agricultural production to increase resistance to diseases and local climates for high yields. This threatens species, especially when there are uncontrolled hybridization and genetic engineering. Eventua...
Science Biology Botany What is a monograph in botany?Question:What is a monograph in botany?Botany:Botany is the branch of biology that studies plants, their structure, genetics, classification, including economic importance. It is sometimes called plant science or phytology....
[41]. Cytogenetic techniques, especially fluorescence in situ hybridization (FISH), have been traditionally used to study CNV. However, the FISH technique can be limited by the subjective evaluation of images and the fact that the procedure is technically demanding and expensive. Moreover, it can...
There are species in which individuals look very different from one another, as well as "cryptic species" that appear identical but are genetically distinct. Hybridization is also common, leading to animals like the liger (a lion-tiger hybrid) and the beefalo (a cross between dome...
The evolution of plants to efficiently transport water and assimilates over long distances is a major evolutionary success that facilitated their growth and colonization of land. Vascular tissues, namely xylem and phloem, are characterized by high specia
During PCR and cycle sequencing, the DNA is first denatured (the double-stranded DNA template becomes single-stranded DNA). A subsequent annealing step allows for hybridization of the oligonucleotide primer close to the sequence of interest. In the extensio...
Danielle Dagenais, Montreal Ecologists are calling upon landscape architects and planners to join their teams: as partners, or as wallflowers. Can genuine hybridization occur? Susannah Drake, New York The landscape architect can synthesize th...
Restriction fragment length polymorphisms are marker molecules that are used to follow a particular DNA sequence as it passes between cells. It is one of the most common types of molecular markers and is based on the hybridization of cloned DNA to DNA fragments. They are specific to a single ...
nov. Together with the 10-stamen, black-fruited hawthorns in predominantly tetraploid, apomictic, and self-fertile C. douglasii Lindl. and its segregates (discussed in detail in a companion paper), these species are linked by whole genome duplications associated in most cases with hybridization,...
In light of all of this, the conclusion has been drawn that the model of the reinforcement of incompatibility in zones of repeated contact with hybridization is not supported by the data, as is the character displacement model that follows from it. The reasons for the popularity of this ...
