MCQ (Single Correct) +4 −1
The phenomenon of offspring nematodes developing from unfertilized eggs happens in:
अनिषेचित अंडों (Unfertilized eggs) से संतति सूत्रकृमियों के विकसित होने की परिघटना क्या कहलाती है?

Parthenogenesis is the biological mode of reproduction in which embryos develop from unfertilized eggs without contribution from a male gamete. It is very common among plant-parasitic nematodes, particularly species of Meloidogyne (such as M. incognita, which reproduces by obligate mitotic parthenogenesis) and Tylenchulus semipenetrans.

अनिषेचित अंडों से सीधे नए जीवों के निर्माण की प्रक्रिया को 'अनिषेकजनन' (Parthenogenesis) कहा जाता है। मेलोइडोगाइन इन्कॉग्निटा (Meloidogyne incognita) सहित कई पादप परजीवी सूत्रकृमि इसी विधि से बिना नर के अपनी संतति उत्पन्न करते हैं।
