Sex determination in bees. II. Additivity of maleness genes in Apis mellifera.
نویسنده
چکیده
Twenty-two randomly taken morphological characters were used in order to estimate the Mahalanobis generalized distance between diploid males, diploid workers, haploid males and triploid workers. It was found that adult diploid males are metamales and triploid females are slightly masculinized. These facts indicate that the maleness genesare slightly additive.

Molecular basis of sex determination in haplodiploids.
Sex in many species of Hymenoptera (ants, bees and wasps) is determined by a single locus that is heterozygous in females and hemizygous in (haploid) males. Beye and colleagues have now cloned the csd locus in the honeybee Apis mellifera and provide functional evidence that this gene is the primary switch in the sex-determination cascade of honeybees and possibly all Hymenoptera.
متن کاملSex Determination in Honeybees: Two Separate Mechanisms Induce and Maintain the Female Pathway
Organisms have evolved a bewildering diversity of mechanisms to generate the two sexes. The honeybee (Apis mellifera) employs an interesting system in which sex is determined by heterozygosity at a single locus (the Sex Determination Locus) harbouring the complementary sex determiner (csd) gene. Bees heterozygous at Sex Determination Locus are females, whereas bees homozygous or hemizygous are ...

Objectives: Royal jelly (RJ), a secretion of both the hypopharyngeal and mandibular glands of nurse workers, is believed to play a central role in honeybee queen development. Important component of royal jelly are proteins which form about 50% of the dry mass of RJ. Major royal jelly proteins (MRJPs) are the dominant proteinaceous component of royal jelly and constitute about 82-90% of total pr...

The first step in fundamental breeding of any living organism is the determination of its genetic make-up. To investigate the genetic make-up of the European honeybee (Apis mellifera L.) in Iran, some research attempts were made during the years 1992-1996 in which the bee's relationship with some exotic races were determined through the application of morphological methods. For this purpose 130...
متن کاملComparison of acute effects of heroin and Kerack on sensory and motor activity of honey bees (Apis mellifera)
Objective(s):Previous studies demonstrated a functional similarity between vertebrate and honey bee nervous systems. The aim of the present study was to compare the effects of heroin and Iranian street Kerack, a combination of heroin and caffeine, on sensory threshold and locomotor activity in honey bees. Materials and Methods: All drugs were given orally to honey bees 30 min before each exper...
