Created by StemPy LabA cross is expected to give a ratio of dominant to recessive plants. A sample of plants is counted. The test uses the chi-square statistic and the critical value (5% level, 1 degree of freedom); the ratio is rejected when chi-square is greater than this value. Fewer recessive plants than expected are found. What is the largest number of recessive plants in the sample at which the ratio is still rejected?

← In a large town of 8000 people that mates at random for the ABO system, 25% have blood group O and 39% have blood group A. The alleles are I^A, I^B and i, and the population is in Hardy-Weinberg equilibrium. How many people are expected to have the genotype I^Ai? Give a whole number.An enzyme follows Michaelis-Menten kinetics with Vmax = 200 µmol min⁻¹ and Km = 2.0 mM. At a substrate concentration of 4.0 mM it works at a certain rate. A competitive inhibitor with Ki = 1.5 mM is then added at 3.0 mM. To bring the rate back to its original value, the substrate concentration must be raised to what value, in mM? Give a whole number. →
