Embryonic development in house fly eggs fertilized with genetically deficient sperm.
In house flies, Musca domestica L., eggs fertilized with sperm that have chromosome deficiencies and duplications do not hatch, but develop to a stage where a fully differentiated, prehatch larva is formed. Fifteen different chromosome translocations involving most of the 10 arms of the 5 autosomes were studied by crossing male translocation heterozygotes to normal females. Egg hatch was reduce...
متن کاملFull-term development after transplantation of parthenogenetic embryonic nuclei into fertilized mouse eggs.
Diploid parthenogenetically activated oocytes were obtained after gonadotropin-induced ovulation of virgin females of the LT/Sv (LT) inbred mouse strain. These oocytes cleave spontaneously and develop into blastocysts which implant in the uterus but die within a few days. We examined the developmental potential of nuclei from parthenogenetic embryos after transplantation into fertilized eggs. T...
متن کاملEmbryonic development in human oocytes fertilized by split insemination
OBJECTIVE To compare the laboratory outcomes of intracytoplasmic sperm injection (ICSI) and conventional insemination using sibling oocytes in poor prognosis IVF cycles where ICSI is not indicated. METHODS Couples undergoing IVF with following conditions were enrolled: history of more than 3 years of unexplained infertility, history of ≥3 failed intrauterine insemination, leukocytospermia or ...
متن کاملPronuclear Microinjection of Rabbit Fertilized Eggs
Although, the first transgenic animal was produced more than 30 years ago, there are still many factors limiting efficiency of transgenesis. One of them is the low rate of transgene incorporation into the genome of microinjected eggs. This mini-review summarizes recent research methods based on pronuclear microinjection of rabbit fertilized eggs in order to reach higher efficiency of transgene ...
متن کاملStable fly, house fly (Diptera: Muscidae), and other nuisance fly development in poultry litter associated with horticultural crop production.
Poultry litter usage in horticultural crop production is a contributor to nuisance fly populations, in particular stable flies (Stomoxys calcitrans L.) and house flies (Musca domestica L.). Extrapolation of adult emergence data suggests that approximately 1.5 million house flies and 0.2 million stable flies are emerging on average from every hectare of poultry litter applied as a preplant ferti...
