Three linked genes $A$ , $B$ and $C$ are mapped by test crosses. The percentage of recombinant progeny is $10\%$ for the pair $A$ and $B$ , $15\%$ for $B$ and $C$ , and $23\%$ for $A$ and $C$ . The order of the genes is not given. Which of the following statements are correct? One or more options may be correct.

One or more options are correct. Tick all the correct ones: a wrong option costs marks, and a part-right answer earns part of the marks.

← In a large population that mates at random, 9% of people show an autosomal recessive trait. The population is in Hardy-Weinberg equilibrium. Which of the following statements are correct? One or more options may be correct.An enzyme follows Michaelis-Menten kinetics. A reversible inhibitor is added at a concentration equal to its Ki. Consider the enzyme with a competitive inhibitor and, in a separate experiment, with a pure non-competitive inhibitor (it binds the free enzyme and the enzyme with substrate equally well) at the same concentration. Which of the following statements are correct? One or more options may be correct. →
