Thedreaded pathogenic bacterium J. grocious makes a toxin called BalD. There are two allelic forms of balD, with the balD-1 allele encoding the more potent form of the toxin, and balD-2 allele encoding the less potent form of the toxin. Every person in Champaign-Urbana is infected with one of two possible strains of J. grocious, which differ only in whether the strain carries balD-1 allele or balD-2 allele. If the allelic frequency of J. grocious strains carrying the balD-1 allele is 0.8 in Champaign (population = 80,000), and 0.6 in (Urbana = 50,000), then what is the allelic frequency of J. grocious strains carrying the less toxic balD allele within the population of the combined cities of Champaign-Urbana?

the answer to your question is:

c. complementary base-pairing

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.
