Attempt to define morphological parameters enabling sex determination of Ips typographus (Linaeus, 1758) (Coleoptera: Curculionidae: Scolytinae) using PCA and CLU
spruce bark beetle principal components analysis cluster analysis
2015/5/5
There are only two known methods for determining the sex of Ips typographus (L.) – dissection that cannot be used with live beetles and by distinguishing between the density of the hairs on the head, ...
Conception rate after sex determination and cryopreservation of D7 bovine embryos
cattle superovulation sexing
2015/4/8
The aim of this study was to evaluate conception rate after sex determination and subsequent freezing of Day 7 (D7) bovine embryos and to compare it with transfer of fresh female embryos. High quality...
Lower quality bovine embryos may be successfully used for sex determination
cattle embryo superovulation sex determination polymerase chain reaction embryo transfer
2015/3/13
The aim of this study was to evaluate the effect of sex determination procedures in Day 7 to Day 8 bovine embryos of various quality. For the purposes of comparison we used high quality (HQ) as well a...

Cattle Meat Sex Determination Meat Quality DEAD Box Protein Gene
2016/5/10
Determination of sex origin of cattle meat by fast and reliable molecular methods is an important measure to ensure correct allocation of export refunds particularly in European countries and also fem...
Robustness Against Extinction by Stochastic Sex Determination in Small Populations
Robustness Against Extinction Stochastic Sex Determination Small Populations Populations and Evolution
2012/5/2
Sexually reproducing populations with small number of individuals may go extinct by stochastic fluctuations in sex determination, causing all their members to become male or female in a generation. In...
Amplification of Porcine SRY Gene for Sex Determination
SRY Gene Sex Determination Sperm Sorting Duplex PCR
2016/4/29
The separation of X and Y chromosome-bearing sperm is of use in many aspects of livestock maintenance. In this study, we sought to determine the difference in DNA content between X- and Y-bearing sper...

cattle embryo superovulation splitting
2015/3/17
The aim of this study was to evaluate the efficiency of sex determination after microsurgical splitting
of D7 (Day 7) bovine embryos and to test the conception rate after subsequent transfer of fema...
鸟类的性别决定是一个多基因参与的级联调控过程。这一过程受Z染色体连锁的DMRT1基因, W染色体连锁的PKC1W和其它多种因子共同调控。本文综述了性别决定基因及其功能、性别鉴定方法等方面的研究进展。
Avian sex determination is a multiple gene regulation cascade. Genes such as the Z chromosome-link...
Transformer基因与果蝇和线虫的性别决定Transformer Genes and Sex Determination of C. elegans and D.melanogaster
线虫 果蝇 性别决定 C.elegans D.melanogaster sex determination
2007/12/5
黑腹果蝇(Drosophila melanogaster)和秀丽隐杆线虫(Caeborhabditis elegans)的性别决定的问题已研究得比较详细,且transformer基因是这两种生物性别决定中最重要的基因之一,其有关的性别决定研究在近几年取得了很大的进展。本文就线虫和果蝇的transformer基因及其相关基因的特性与功能进行了特别介绍,并在此基础上对其性别决定的分子机制进行初步的比较...
Two cues for sex determination inGammarus duebeni:Adaptive variation in environmental sex determination?
sex determination Gammarus duebeni Adaptive variation environmental sex determination
2014/5/8
In the crustacean Gammarus duebeni, sex is determined by the interaction of a number of environmental, genetic and parasitic factors, which may, in turn, influence sex ratios and population dynamics. ...
