Q.5

Fish Biotechnology- ICAR JRF/SRF 2024 (Q.36)

MCQ (Single Correct) +4 −1

Allozyme markers are less polymorphic because

coding sequences are conserved and genetic code is degenerate coding sequences are conserved and some amino acid changes remain undetected polymorphism remain undetected due to limitations of electrophoresis Coding sequences are conserved, genetic code is degenerate, and electrophoresis limits detection
