Quizplus · Accepted Answer

The first offspring from the parents are called the first filial generation, which can be abbreviated as F1. Therefore, option B, which represents F_1., is the correct answer. Option C represents F_2., which would refer to the second filial generation, or F2. Options D and E are incorrect as they refer to types of crosses rather than a specific generation of offspring. Option A is not a valid representation of filial generation labeling.
