BREEDING AND GENETICS Heterosis and DNA Fingerprinting in Chickens
Enhancement of performance in traits of economic importance by use of heterosis (hybrid vigor) is routine in poultry breeding. There is, however, no reliable method to predict the level of heterosis that will occur from the mating of individuals from two populations. DNA fingerprints (DFP) were used as a measure of genetic distance between mating pairs of chickens where each individual of a pai...

Does DNA methylation pattern mark generative development in winter rape?
In this paper we report on changes in DNA methylation pattern in rape apices and leaves during transition from vegetative to reproductive stage due to grafting and/or vernalization. Grafted plants of winter rape (Brassica napus L., var. "Górczański") (stock from vernalized, scion from non-vernalized plants) were used together with vernalized non-grafted plants. In addition, methylation status w...
متن کاملAdenine Nucleotide Changes during Cold Acclimation of Winter Rape Plants.
During the first stage of hardening of winter rape plants (Brassica napus L. var. oleifera L., cv. Górczański), marked increase of ATP content in leaves was observed. Lowering the temperature from 5 to 0 C (the second stage of hardening) had no further effect on ATP content. In roots, not capable of hardening, pronounced decrease of ATP content was noted after prolonged exposure to cold. It was...
متن کاملEffect of Including Inbreeding, Heterosis and Recombination Loss in Prediction of Breeding Values for Fertility Traits
Inbreeding results from the mating of related individuals and is becoming increasingly important in domestic livestock populations. Inbreeding depression is the reduction of the mean phenotypic value, particularly for traits connected with reproduction or fitness (Miglior et al., 1992). Inbreeding depression has been shown to decrease milk production by approximately 9-26 kg of milk per lactati...
