PGD gender selection for non-Mendelian disorders with unequal sex incidence.
Preimplantation genetic diagnosis (PGD) was originally developed for couples whose potential offspring were at risk of severe Mendelian disorders, but has since been extended to other indications. One possible use of PGD is to perform gender selection for couples whose offspring are at increased risk of disorders that do not follow Mendelian inheritance, but which are substantially more common ...
متن کاملWhy Mendelian segregation?
The discovery of alleles that are able to distort segregation during meiosis in their favour raises the question of why Mendelian segregation is the rule and segregation distortion the exception. Previous research on this topic was limited by an unrealistic assumption: equal segregation in the two sexes. Ubeda and Haig [(2005) Genetics 170, 1345-1357] provide a new model allowing sex-specific s...
متن کاملDisentangling the effect of genes, the environment and chance on sex ratio variation in a wild bird population.
Sex ratio theory proposes that the equal sex ratio typically observed in birds and mammals is the result of natural selection. However, in species with chromosomal sex determination, the same 1 : 1 sex ratio is expected under random Mendelian segregation. Here, we present an analysis of 14 years of sex ratio data for a population of song sparrows (Melospiza melodia) on Mandarte Island, at the n...
متن کاملDetection of Mendelian and Parent-of-origin Quantitative Trait Loci for Meat Quality in a Cross between Korean Native Pig and Landrace
This study was conducted to detect quantitative trait loci (QTL) affecting meat quality in an F2 reference population of Korean native pig and Landrace crossbreds. The three-generation mapping population was generated with 411 progeny from 38 F2 fullsib families, and 133 genetic markers were used to produce a sex-average map of the 17 autosomes. The data set was analyzed using least squares Men...
متن کاملSearching the genome of beluga(Husohuso) for sex markers based on targeted Bulked SegregantAnalysis (BSA)
In sturgeon aquaculture, where the main purpose is caviar production, a reliable method is needed to separate fish according to gender. Currently, due to the lack of external sexual dimorphism, the fish are sexed by an invasive surgical examination of the gonads. Development of a non-invasive procedure for sexing fish based on genetic markers is of special interest. In the present study we empl...
