The laboratory mouse is recognized as the pre-eminent model for genetic research. Awareness of chromosomal patterns of experimental animals increases their value for a variety of different fields of study. We aimed to study mitotic chromosome preparations from NIH, C57BL/6 and Razi strains of mice, which are outbred, inbred and partially inbred laboratory mice respectively. Bone marrow cells we...
A panel of seven maize inbred lines belonging to Zemun Polje commercial pool were genotypized using SNPs bead chip. 21 hybrids, developed according the half dialel mating design, tested in field together with per se. The goal study was determine genetic distance among and establish whether there a significant correlation between parental inbreds grain yield, specific combining abilities (SCA) h...
Results of the analysis are presented of the effect of inbreeding on selected reproduction traits and body weight in a Booroola flock kept closed for 14 years at the Institute of Genetics and Animal Breeding, Jastrzębiec. The mean inbred in lambs rose linearly until 2002, when it reached the level of 9.81%, ranging from 0 to 31.7%. No inbred effect was observed on ovulation rate, fertility, lit...
the aim of this study was evaluation of some of characters, estimation of their heritability and their relationship in 104 recombinant inbred lines population of durum wheat under pot and field conditions. the inbred lines, their parents and control genotypes were evaluated in completely randomized design in 3 replications at pot study and in augment design at field condition. analysis of varia...
Accurately estimating inbreeding is important because inbreeding reduces fitness and production traits in populations. We analyzed information from pedigrees and from microsatellite markers to estimate inbreeding in a line of Japanese quail derived from a randombred line (QO) and maintained for 17 generations by pedigreed matings of brothers to groups of sisters. Pedigree data were used to calc...
In social animals, inbreeding depression may manifest by compromising care or resources individuals receive from inbred group members. We studied the effects of worker inbreeding on colony productivity and investment in the ant Formica exsecta. The production of biomass decreased with increasing inbreeding, as did biomass produced per worker. Inbred colonies produced fewer gynes (unmated reprod...
In this report, we assess the humoral immune response in inbred strains of mice immunized with baculovirus-derived recombinant HIV-1 gp160 (rgp160). Six inbred strains of mice were each immunized with two different concns (5 and 50 micrograms) of rgp160, and the antibody response to rgp160 and synthetic peptides which define distinct gp160 epitopes was examined. Within a given inbred strain of ...
The aim of this study was to assess the usefulness of the inbred rat model for studies of genetic influences on skeletal fragility. We characterized bone mass, geometry, and skeletal biomechanics in 11 inbred strains of rats. This study showed that considerable variation exists in bone structure, areal bone mineral density (aBMD), and fragility phenotypes among inbred strains of rats. Interesti...
The propensity to capture and mobilize gene fragments by the highly abundant Helitron family of transposable elements likely impacts the evolution of genes in Zea mays. These elements provide a substrate for natural selection by giving birth to chimeric transcripts by intertwining exons of disparate genes. They also capture flanking exons by read-through transcription. Here, we describe the exp...
