Summary
Honey bee queens store drone sperm for life. This study found patriline distribution in a single queen
Area of Science:
- * Apiculture and Reproductive Biology
- * Behavioral Ecology
Background:
- * Honey bee queens mate once and store sperm from multiple drones for their lifetime.
- * Sperm usage is presumed random, maintaining consistent patriline distribution over time.
Purpose of the Study:
- * To investigate long-term changes in patriline distribution within a single honey bee colony.
- * To analyze sperm usage patterns over three years in relation to queen age.
Main Methods:
- * Microsatellite markers were used to assign progeny to patrilines.
- * Samples were collected from a single naturally mated queen at ages two, three, and four years.
- * Patriline distribution was analyzed within and across foraging seasons and years.
Main Results:
- * No significant changes in patriline distribution were observed within foraging seasons.
- * Significant differences in patriline composition were found when comparing across the three analyzed years.
- * A trend towards more equal patriline representation over the three-year period was observed.
Conclusions:
- * Patriline distribution can change significantly over multiple years, contrary to the assumption of random sperm usage.
- * Long-term changes may be influenced by mixing dynamics within the queen's spermatheca.
- * Further research is needed to assess individual and population variations in sperm usage patterns.

Most altruistic behavior—in which one animal helps another at a cost to themselves—occurs between relatives. Scientists think these altruistic behaviors evolved because they increase the inclusive fitness of the animal providing help.

Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying...

Flowers are the reproductive, seed-producing structures of angiosperms. Typically, flowers consist of sepals, petals, stamens, and carpels. Sepals and petals are the vegetative flower organs. Stamens and carpels are the reproductive organs.

When crossing pea plants, Mendel noticed that one of the parental traits would sometimes disappear in the first generation of offspring, called the F1 generation, and could reappear in the next generation (F2). He concluded that one of the traits must be dominant over the other, thereby causing masking of one trait in the F1 generation. When he crossed the F1 plants, he found that 75% of the offspring in the F2 generation had the dominant phenotype, while 25% had the recessive phenotype.

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
