بررسی امکان تولید جمعیت تمام ماده تریپلوئید قزلآلای رنگینکمان (Oncorhynchus mykiss)
In order to reduce the adverse effects of sexual maturation on growth and survival of rainbow trout, production possibility of all-female triploid was investigated by means of early heat shock on eggs fertilized by masculinized male’s sperm. Fish ploidy level was determined by erythrocyte size measurement and confirmed by gill nucleolus (NORs) counting as well as chromosome number. Sexual ratio...
متن کاملEffect of thermal stress on some hematological parameters of diploid and triploid Rainbow trout (Oncorhynchus mykiss)
Temperature fluctuation is one of the most common stressors during fish transportation and aquaculture condition. Triploid rainbow trout (Oncorhynchus mykiss) get more attention because of its sterility. In this study, 24 rainbow trout belong to diploid and triploid group, average weight 13±0.23 g were subjected to temperature change from 13 to 20 ºC, and kept under tension for 10 min. Before a...
متن کاملGenomic constitution and atypical reproduction in polyploid and unisexual lineages of the Misgurnus loach, a teleost fish.
The loach (Misgurnus anguillicaudatus) is an excellent animal model to elucidate biological origin and evolutionary significance of genome duplication and unisexual reproduction because artificially induced and naturally occurring polyploids and parthenogenetic (gynogenetic, androgenetic) animals can be compared. First, we summarize the chromosome manipulation techniques to induce triploids and...

متن کاملNo patrigenes required for femaleness in the haplodiploid wasp Nasonia vitripennis.
The parasitoid wasp Nasonia vitripennis is an emerging model organism for developmental and behavioral genetics. It reproduces by haplodiploidy; males typically develop parthenogenetically from haploid eggs and females from fertilized diploid eggs. A polyploid mutant strain is available in which females are triploid and lay haploid and diploid eggs that normally develop into males when unfertil...
