Random Amplified Polymorphic DNA (RAPD) analysis of Pistacia vera L. was used to distinguishing sex type in progeny plants. Varied genotypes of the pistachio were analyzed by PCR amplification of a ten base primer previously found to be linked to the expression of a 945bp amplification band in female trees and its absence in males. Results revealed that genetic material from cultivar samples am...

Although interest in beef-on-dairy breeding strategies is intensifying, little actually known of the performance differences between beef-sired male and female progeny dairy cows. The objective was therefore to use a large cross-sectional database up 1,389,670 animals investigate if existed generated from matings; focus on characteristics both producer (i.e., gestation length, calving performan...

George H. Shull, while working as a corn geneticist at the Cold Spring Harbor Laboratory from 1904 to 1915, observed that when two different pure-bred lines of corn were crossbred the resulting progeny exhibited physical traits superior to those of the parents (Glass, 2010). Shull described the offspring of pure-bred crosses as having increased heartiness, size, fruitfulness, speed of developme...

Accurate pedigree information is critical to animal breeding systems to ensure the highest rate of genetic gain and management of inbreeding. The abundance of available genomic data, together with development of high throughput genotyping platforms, means that single nucleotide polymorphisms (SNPs) are now the DNA marker of choice for genomic selection studies. Furthermore the superior qualitie...

the influence of parasitoids on population dynamics is affected by host instar preference. the preference pattern of host instars is not fixed and is modified by the availability and relative abundance of host instars, intensity of defensive behaviors in a particular instar, and also maternal effects of the female forager. in this study, host instar preference of the thelytokous strain of lysip...

The objective of the study was to determine whether Parkia platycephala families with superior morphophysiological traits perform consistently across four stages early development (plantlets, seedlings, and juveniles at 34 60 months), as a means assess possibility conducting pre-selection. For 21 traits, following genetic parameters were estimated: heritability, coefficients variation (genetic,...
