Genetic parameters of cross‐ and purebred poultry
British Poultry Science, 1973Synopsis Heritabilities were estimated from sire and dam components for egg production traits in four generations of two pure‐lines and their reciprocal crosses. Heritabilities in cross‐breds, as estimated from the sire components of variance, were larger than in pure‐breds for production and sexual maturity.

The genetic detection of natural crossing in blackberry
Genetica, 19551. 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.

Population genetics of unequal crossing over
Journal of Molecular Evolution, 1975The population genetics of unequal crossing over was examined for an infinite population with random mating. The following cases were considered: 1. There is an initial portion of duplicated genes which offer the opportunity for unequal crossing over, but the primary event leading to the duplication does not occur any more (model 1a). 2.

Molecular ontogenesis and molecular genetics in the crosses of toads [PDF]
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 analysis of the mouse using interspecific crosses
Trends in Genetics, 1988Abstract 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.

A teaching framework for cross‐cultural genetic counseling
Journal of Genetic Counseling, 1993AbstractThe 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.

Genetic interpretation and analysis of diallel crosses with animals
Theoretical and Applied Genetics, 1983A genetic framework was developed for the interpretation of statistical parameters estimated from a diallel experiment among a fixed set of lines. These included average direct genetic, average maternal genetic, general combining ability, reciprocal, and line and specific direct and maternal heterotic effects.

The growth of genome-wide and Candidate Gene Association Studies have elevated genetic causality in medicine and behavioral science. This chapter explores the concept of causality as it has been applied in genetic explanations and distinguishes the varieties of methods used to establish genetic causation.
