20. The concept of recon was proposed by Seymour Benzerby studying recombination between (1) lysis mutants of bacteriophage T4 (2) white eye mutants of Drosophila melanogaster. (3) biochemical mutants of […]

How many complementation groups do the following mutants m1 to m6 come under? Result of complementary between different mutants   m1 m2 m3 m4 m5 m6 m1 – – + […]

The results of a complementation test for five independent mutants (1 to 6) are summarized below 1 2 3 4 5 6   0 + 0 + + 0 1 […]

The results of a complementation test for five independent mutants (1 to 5) are summarized below: 1 2 3 4 5   0 0 0 + + 1   0 […]

16. Four different mutant lines showing similar phenotype were identified from a genetic screen. When genetic crosses among these mutants were carried out, the first mutant was found to complement […]

15. When two mutants having the same phenotype were crossed, the progeny obtained showed a wild-type phenotype. Thus the mutations are (1) non-allelic. (2) allelic. (3) segregating from each other. […]

14. Two mutants of Drosophila melanogaster. one showing light red eye colour and the other showing dark brown eye colour, were crossed. In F1 all flies showed normal red eye […]

13. A cis-trans complementation test is carried out to identify (1) if two mutations are allelic in nature. (2) if two genes interact with one another. (3) the number of […]

12. A fly with apricot coloured eye was crossed With a septa eyed fly of opposite sex. In Fl all flies were Wild tvpe. The genes responsible for the two […]

11. In a heterozygous two recessive mutation at different site will give mutant phenotype when genes involved are (1) Allelic and placed in cis (2) Allelic and placed in trans […]
