Sheâll even pluck some breast feathers so that her bare skin can be right next to the eggs, all the better to monitor them and boost humidity. A hen will hatch pretty much any kind of eggs you put under her. Chicken, guinea, duck; your imagination â and pen space! â is the limit. Not all hens are good broodies.
DNAâDNA hybridization generally refers to a molecular biology technique that measures the degree of genetic similarity between pools of DNA sequences. It is usually used to determine the genetic distance between two organisms.This has been used a lot in phylogeny and taxonomy.he DNA of one organism is labeled, then mixed with the unlabeled DNA to be compared against. The mixture is incubated to allow DNA strands to dissociate and renewal forming hybrid double-stranded DNA.
Fluorescent in situ hybridization is a molecular cytogenetic technique that uses fluorescent probes that bind to only those parts of the chromosome with a high degree of sequence complementarity. It was developed by biomedical researchers in the early 1980s and is used to detect and localize the presence or absence of specific DNA sequences on chromosomes. Fluorescence microscopy can be used to find out where the fluorescent probe is bound to the chromosomes. FISH is often used for finding speci
