The aim of the present study was to develop a genetic sex marker for the pointed gourd (Trichosanthes dioica Roxb.) to allow gender determination at any stage in the life cycle. Screening of genomic DNA with intersimple sequence repeat (ISSR) primers was used to discover sex-specific touch-down polymerase chain reaction (Td-PCR) amplification products. Using pooled DNA from male and female geno...

Background Gender and sex differences in the development of children adolescents are commonly found psychiatric examination. Family developmental history is an important part clinical diagnostic interview, basic examination technique. Attention-deficit/hyperactivity disorder (ADHD) associated with diagnosis-specific markers family history. However, it unclear to what extent ADHD-specific signs ...

CONTEXT The molecular basis for about 70-80% of 46,XY sex-reversed females remains unexplained, because they carry normal copies of the genes (SRY, SOX9, DAX1, DMRT, SF1, WT1) involved in sex determination pathway. OBJECTIVE The objective of this study is to map the chromosomal locus responsible for an unexplained sex-reversed phenotype. DESIGN The study implemented a genome-wide scan using...

Eucommia ulmoides Oliv. is a dioecious species. Currently, there is no method to identify the sex during the juvenile stage that lasts a relatively long time. This study aimed to develop a sex specific Amplified Fragment Length Polymorphism (AFLP) marker for Eucommia ulmoides Oliv. Of a total of 64 AFLP primer combinations screened, primer combination E-ACA/M-CTT produced a 350 bp male-specific...

Genetic crosses between the dioecious Bryonia dioica (Cucurbitaceae) and the monoecious B. alba in 1903 provided the first clear evidence for Mendelian inheritance of dioecy and made B. dioica the first organism for which XY sex-determination was experimentally proven. Applying molecular tools to this system, we developed a sex-linked sequence-characterized amplified region (SCAR) marker for B....

Most dioecious plants do not exhibit discernible sexual dimorphism before sexual maturity. Therefore, it is impossible to address any sex-related questions during the prereproductive phase unless a genetic sex marker is available for gender determination. The aim of the present study was to develop a genetic sex marker for the moss Pseudocalliergon trifarium to allow gender and sex ratio determ...

Abstract Sex has a significant effect on various traits among dioecious plants. In this analysis of the sex radial growth and wood density numerous 20-year-old trees Populus deltoides growing in common garden, male performed better than females growth, but did not significantly affect density. Growth rate were weakly negatively correlated. selection is also critical for controlling seed-hair po...

The ability to determine the sex of an individual based on DNA evidence can be crucial in instances such as identification of victims of mass disaster, missing persons investigations, and sexual assault cases. The Y chromosome marker amelogenin is currently in widespread use for determination of chromosomal sex of an unknown DNA donor and differentiating the relative contributions of male and f...

the study investigates the possibility of sex determination of rainbow trout (oncorhynchus mykiss)using molecular screen for products monosex of populations. 35 caudal fin tissue samples wereobtained from karaj rainbow trout mature population and then genomic dna was extracted andmarker loci amplified. polymerase chain reaction (pcr) was setup based on two omyfa andomyfatu markers for amplifica...
