Carry out matings between hybrids. b. Find true-breeding varieties that differ in phenotype for the trait. c. Testcross the offspring of hybrids to determine their genotypes. d. Record the phenotypes and frequencies of the offspring of hybrids. e. Examine and record the hybrid phenotypes. f. Mate true-breeding varieties with one another to obtain a hybrid.

Giovanni Norris · Answer 1

The correct order would be b, f, e, a, d, and c.

Explanation:

In the given case, the first step is to determine the true-breeding varieties, which differs from the trait's phenotype. After that mating needs to be done between the true-breeding varieties to get a hybrid.

Post mating, examination, and recording of the hybrid phenotypes are needed to be done. After that, the hybrids need to get mate with each other. After that phenotypes and frequencies of the hybrid's offspring are recorded. Finally, the testcross of the hybrids' offspring is performed to find the genotypes.
