The evolutionary stability of cross-sex, cross-trait genetic covariances.

Evolution; international journal of organic evolution, 2014
Although knowledge of the selective agents behind the evolution of sexual dimorphism has advanced considerably in recent years, we still lack a clear understanding of the evolutionary durability of cross-sex genetic covariances that often constrain its evolution.

The genetic detection of natural crossing in blackberry

Genetica, 1955
1. The pollination system in 4x blackberry was studied from vicinism (cross-pollination with neighbouring plants) in a row of Merton Thornless plants situated between rows of thornyRubus, using glandularv. eglandular cotyledons as markers. 2. Average hybridization was 17%, ranging from 5 to 32% in different flower samples.

Dissecting genetic correlation and pleiotropy through a genetic cross

2023
Abstract Genetic correlation represents an important class of evolutionary constraint, which is itself evolvable. Empirical studies have found mixed results on whether genetic correlations change rapidly or slowly. This uncertainty challenges our ability to predict the outcome of selection.

Bearing crosses: A historiography of genetics and embryology

American Journal of Medical Genetics, 1998
As we construct the fusion of medical embryology and medical genetics, it is important to be aware of how the history of genetics has been written to exclude embryology. This article looks at the rhetoric of genetics and how that rhetoric fits a paradigm of supersessionism.

To cross or not to cross: a genetic analysis of guidance at the midline.

Perspectives on developmental neurobiology, 1994
Previous studies have led to the suggestion that the midline of the developing Drosophila central nervous system might serve a dual function during growth cone guidance, providing attractive signals for those growth cones that project across the midline, and at the same time repulsive signals for those growth cones that stay on only their own side.

Genetic analysis of the mouse using interspecific crosses

Trends in Genetics, 1988
Abstract Interspecific mouse crosses used in conjunction with cloned sequences are facilitating gene localization and high resolution meiotic analysis of the mouse genome. Determination of the recombination breakpoints on individual chromosomes allows gene ordering by ‘pedigree analysis' rather than by recombination distance estimation alone.

Molecular ontogenesis and molecular genetics in the crosses of toads

Experientia, 1961
E stata studiata la comparsa di antigeni nel corso dello sviluppo di due specie di rospi:Bufo bufo eB. viridis e dei loro incroci reciproci. Alcuni antigeni al loro primo apparire precipitano solo con l'antisiero specie-specifico e, solo dopo lo stadio di bottone caudale, sono precipitati anche dall'antisiero dell'altra specie; questo viene ...

Genetic programming for cross-task knowledge sharing

Proceedings of the 9th annual conference on Genetic and evolutionary computation, 2007
We consider multitask learning of visual concepts within genetic programming (GP) framework. The proposed method evolves a population of GP individuals, with each of them composed of several GP trees that process visual primitives derived from input images.

Cross Dock Scheduling Using Genetic Algorithms

2007 International Symposium on Computational Intelligence in Robotics and Automation, 2007
Cross docking is a distribution system in which the merchandise received at a warehouse or distribution center is not stocked but immediately prepared for onward shipment. In other words, cross docking is the transfer of inward deliveries from the point of reception directly to the point of delivery with limited or no interim storage. One way to reduce

A teaching framework for cross‐cultural genetic counseling

Journal of Genetic Counseling, 1993
AbstractThe increasing diversity of American society has brought growing recognition of the need to bridge cultures in the delivery of genetic counseling services. New immigrants and members of diverse ethnic groups face multiple barriers to genetic counseling services.
