Functionally reproductive diploid and haploid males in an inbreeding hymenopteran with complementary sex determination.
It has become a matter of orthodoxy that among wasps, ants, bees, and other insects in the order Hymenoptera, only uniparental haploid males that arise from unfertilized eggs are capable of reproduction. This idea is of interest because the best understood and perhaps most widespread sex determination system among these insects [known as single locus complementary sex determination (sl-CSD)] do...
متن کاملEpigenetic inheritance and genome regulation: is DNA methylation linked to ploidy in haplodiploid insects?
Organisms show great variation in ploidy level. For example, chromosome copy number varies among cells, individuals and species. One particularly widespread example of ploidy variation is found in haplodiploid taxa, wherein males are typically haploid and females are typically diploid. Despite the prevalence of haplodiploidy, the regulatory consequences of having separate haploid and diploid ge...
متن کاملThe Feasibility Study on the Prediction of Ploidy Levels Base on Pollen Dimensions in Rosa
Ploidy level is one of important factors for plant breeders; therefore models that can predict it are very practical. To estimate of ploidy levels in some species, hybrids and cultivars of Rosa, dimensions of over 500 pollens include pollen length, width and area measured at ABRII. The calculations were carried out in several stages. First, Ploidy levels were regressed with pollen dimensions, a...
متن کاملBRAFV600E mutation and DNA ploidy determination in fine needle aspiration biopsy of papillary thyroid microcarcinoma in a Chinese population
This study aimed to evaluate the diagnostic value of BRAFV600E mutation and DNA ploidy determination for Papillary Thyroid Micro-Carcinoma (PTMC) through fine-needle aspiration. Clinical data, including histology, patient population statistics and clinical results were gathered. Patients’ thyroid-micro-lesions were made into FNA-stained smears, DNA was extracted from the smears for different cy...
متن کاملPloidy tug-of-war: Evolutionary and genetic environments influence the rate of ploidy drive in a human fungal pathogen.
Variation in baseline ploidy is seen throughout the tree of life, yet the factors that determine why one ploidy level is maintained over another remain poorly understood. Experimental evolution studies using asexual fungal microbes with manipulated ploidy levels intriguingly reveals a propensity to return to the historical baseline ploidy, a phenomenon that we term "ploidy drive." We evolved ha...
متن کاملPloidy studies on the large cells of Micrococcus aureus.
The determination of ploidy in bacterial cells has been unsatisfactory in most cases because the criteria of ploidy in higher forms can not as yet be applied directly to bacteria. The best evidence of diploidy in bacteria has been in the various "Het" strains of Escherichia coli strain K-I2 developed by Lederberg et al. (1951). Unfortunately, genetic recombination has not been found in many bac...
