The permissive temperature is the temperature at which a temperature-sensitive mutant gene product takes on a normal, functional phenotype. [2] When a temperature-sensitive mutant is grown in a permissive condition, the mutant gene product behaves normally (meaning that the phenotype is not observed), even if there is a mutant allele present.
Demaree also described a swarm prevention method in 1884, but that was a two-hive system that is unrelated to modern "demareeing". [2] As with many swarm prevention methods, demareeing involves separating of the queen and forager bees from the nurse bees. The theory is that forager bees will think that the hive has swarmed if there is a drastic ...
A swarm typically contains about half the workers together with the old queen, while the new queen stays back with the remaining workers in the original hive. When honey bees emerge from a hive to form a swarm, they may gather on a branch of a tree or on a bush only a few meters from the hive.
In genetics, a missense mutation is a point mutation in which a single nucleotide change results in a codon that codes for a different amino acid. [1] It is a type of nonsynonymous substitution . Substitution of protein from DNA mutations
The term "honey bee" means a bee of the species Apis mellifera which descend from bees that originated in Africa. Differences in the colors of bees may be more pronounced in queens and drones; workers are much less easily differentiated by color. Drones are produced from the unfertilized eggs of queens and therefore their genetic ...
One of the possible mutations that occurs is the replacement of a single nucleotide, known as a point mutation. If a point mutation occurs within an expressed region of a gene, an exon, then this will change the codon specifying a particular amino acid in the protein produced by that gene. [2]
Apis dorsata, the rock bee or giant honey bee, is a honey bee of South and Southeast Asia. They are typically around 17–20 mm (0.7–0.8 in) long and nests are mainly built in exposed places far off the ground, like on tree limbs, under cliff overhangs, and under buildings.
A synthetically produced Nasonov pheromone can be used to attract a honey bee swarm to an unoccupied hive or a swarm-catching box. Synthetically produced Nasonov consists of citral and geraniol in a 2:1 ratio. The Nasonov gland was first described in 1882 by the Russian zoologist Nikolai Viktorovich Nasonov.
