MCQ (Single Correct) +4 −1

A crossing of two or more breeds and alternately mating the hybrid females over several generations with males of the original breeds is called:

दो या दो से अधिक नस्लों का संकरण तथा कई पीढ़ियों तक संकर मादाओं का मूल नस्लों के नरों के साथ बारी-बारी से समागम कराना क्या कहलाता है?

Criss crossing क्रिस क्रॉसिंग Back crossing बैक क्रॉसिंग Test crossing टेस्ट क्रॉसिंग Out crossing आउट क्रॉसिंग

Analysis of animal breeding systems:

Criss crossing (rotational crossbreeding) involves mating hybrid females alternately with purebred sires of two or more parental breeds in successive generations to maintain heterosis.
Back crossing refers to crossing an F1 hybrid back to one of its parental pure breeds.
Test crossing is the cross of an individual with a homozygous recessive individual to determine its genotype.
Out crossing is mating of unrelated purebred animals within the same breed.

पशु प्रजनन प्रणालियों का विश्लेषण:

क्रिस क्रॉसिंग (रोटेशनल क्रॉसिंग) में संकर मादाओं को दो या अधिक मूल नस्लों के शुद्ध नर पशुओं से क्रमिक पीढ़ियों में बारी-बारी से संकरित कराया जाता है ताकि संकर ओज बना रहे।
बैक क्रॉसिंग में $F_1$ संकर का संकरण उसके किसी एक जनक शुद्ध नस्ल से कराया जाता है।
टेस्ट क्रॉसिंग में जीनोटाइप निर्धारित करने हेतु किसी व्यष्टि का संकरण समयुग्मजी अप्रभावी जनक से कराया जाता है।
आउट क्रॉसिंग एक ही नस्ल के असंबद्ध शुद्ध पशुओं के मध्य कराया जाने वाला संकरण है।
