karyogamy उदाहरण वाक्य

उदाहरण वाक्य

1. In haploid organisms that lack sexual cycles, karyogamy can also be an important source of genetic variation during the process of forming somatic diploid cells.
2. Nuclear karyogamy and meiosis ( sexual recombination ) occur within the zygospores, which are thought to be long-lived and resistant to adverse conditions.
3. The half-bridge is the site of new SPB assembly, and it also plays a role in cytoplasmic microtubule nucleation during G1 and karyogamy.
4. In the case of dormant spores in eukaryotes, sporogenesis often occurs as a result of fertilization or karyogamy forming a diploid spore equivalent to a zygote.
5. Fusion of the nuclei ( karyogamy ) takes place in the U-shaped cells in the hymenium, and results in the formation of a diploid zygote.
6. The copulated union of multinuclear cells is folloved after a more or less long period dikaryophase, by a pairwise fusion ( karyogamy ) of sexually different nuclei.
7. The nuclei do not immediately fuse, and remain haploid in a n + n state until the very onset of meiosis : this phenomenon is called delayed karyogamy.
8. Karyogamy between these two types of gametangia one being from the A1 sexualtype and the other of the A2 sexual type results in the formation of an overwintering oospore.
9. :Thus in Ascomycota, for example, the nuclei from the two parent individuals ( not genetically identical ) fuse to each other ( karyogamy ) and form the diploid zygote nucleus.
10. In some fungi, two different haploid mating types  if compatible  merge . nuclei, i . e ., one from each parent that eventually undergoes karyogamy and meiosis to complete the sexual cycle.
