Endometrial stromal cells of women with recurrent miscarriage fail to discriminate between high- and low-quality human embryos [PDF]

open access: yes, 2012
Background The aetiology of recurrent miscarriage (RM) remains largely unexplained. Women with RM have a shorter time to pregnancy interval than normally fertile women, which may be due to more frequent implantation of non-viable embryos.

THEORETICAL MODIFICATIONS OF RECIPROCAL RECURRENT SELECTION [PDF]

open access: yesGenetics, 1976
ABSTRACT Reciprocal recurrent selection (RRS), which assumes overdominant loci to be important, alters two genetically different populations to improve their crossbred mean. Individual plants from two populations (A and B) are selfed and also crossed with plants from the reciprocal female tester population (B and A, respectively ...

Enhancing genetic gain through the application of genomic selection in developing irrigated rice for the favorable ecosystem in Bangladesh

open access: yesFrontiers in Genetics, 2023
Increasing selection differential and decreasing cycle time, the rate of genetic improvement can be accelerated. Creating and capturing higher genetic with higher accuracy within the shortest possible time is the prerequisite for enhancing genetic gain ...

The effects on neutral variability of recurrent selective sweeps and background selection [PDF]

open access: yesGenetics, 2018
ABSTRACT Levels of variability and rates of adaptive evolution may be affected by hitchhiking, the effect of selection on evolution at linked sites. Hitchhiking can be caused either by selective sweeps or by background selection, involving the spread of new favorable alleles or the elimination of deleterious mutations,

Utilizing Genomic Selection for Wheat Population Development and Improvement

open access: yesAgronomy, 2022
Wheat (Triticum aestivum L.) breeding programs can take over a decade to release a new variety. However, new methods of selection, such as genomic selection (GS), must be integrated to decrease the time it takes to release new varieties to meet the ...

Strategies for the next cycles of intrapopulation improvement of sour passion fruit [PDF]

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental, 2022
In breeding programs, the identification of genetic variability and knowledge of genetic constitutions existing within segregating populations are of fundamental importance for the success and continuation of the program.

Acacia koa seedling disease tolerance and vigor driven by breeding orchard size

open access: yesFrontiers in Plant Science
Acacia koa Gray (koa) is a Hawaiian endemic tree species that has a long history of use in the islands. In the late 20th century disease started impacting native koa stands, leading to the initiation of seed orchards that were founded from seeds ...
