The claim that a Mytilus galloprovincialis male failed to transmit mtDNA to its sons in controlled crosses is shown to be false. At present there is no evidence for mussel males lacking a paternal mtDNA. This makes unlikely the hypothesis that maternal genomes may become paternally transmitted by invading the germ line of males that lack a paternal genome.

In many gynodioecious species the nuclear inheritance of male fertility is complex and involves multiple (restorer) genes. In addition to restoring plants from the female (male sterile) to the hermaphrodite (male fertile) state, these genes are also thought to play a role in the determination of the quantity of pollen produced by hermaphrodites. The more restorer alleles a hermaphroditic plant ...

Inheritance of fertility restoration was studied in crosses involving ten elite restorer lines of rice viz. BR6839-41-5-1R, BR7013-62-1-1R, BR7011-37-1-2R, BR10R, BR11R, BR12R, BR13R, BR14R, BR15R and BR16R and one male sterile line Jin23A with WA sources of cytoplasmic male sterility. The segregation pattern for pollen fertility of F2 and BC1 populations of crosses involving Jin23A indicated t...

Germ-line mutation induction at mouse minisatellite loci by acute irradiation with x-rays was studied at premeiotic and postmeiotic stages of spermatogenesis. An elevated paternal mutation rate was found after irradiation of premeiotic spermatogonia and stem cells, whereas the frequency of minisatellite mutation after postmeiotic irradiation of spermatids was similar to that in control litters....

To restore the load voltage, Dynamic Voltage Restorer (DVR), which is installed between the supply and a sensitive load, should inject voltage and active power from DVR to the distribution system during voltage sag. Due to the limit of energy storage capacity of DC link, it is necessary the minimize energy injection from DVR. In this paper the techniques of the supply voltage sag compensation i...

This paper introduces the terminology and various issues related to ‘power quality’. The power quality problem is an occurrence manifested as a nonstandard voltage, current or frequency deviations that result in a failure of end use equipment’s. The main occurrence of voltage sag is always considered as one of the major power quality problems and it become severe to industrial customers. Voltag...

in order to investigate the growth curve of broiler chickens at line level, respectively 154 and 144 birds from two paternal lines a and b of a commercial broiler line were used. line a were selected several generations for low feed conversion rate and line b were selected several generation for high body weight. body weight was measured at 1, 4, 7, 10, 14, 17, 21, 28, 35, 42, 49 and 54 days of...
