Question

In the F2 generation of a cross between true-breeding parents that differed in two characteristics, Mendel observed offspring that had combinations of traits not found in the plants of the parental generation. These offspring are called

Answer 1

In his genetic experiments, Mendel observed the F2 generation with trait combinations not seen in the parental generation, known as recombinants.

Step-by-step explanation:

In Gregor Mendel's genetic experiments with pea plants, the offspring from the F1 generation (first filial generation) were allowed to self-pollinate, resulting in the F2 generation (second filial generation). Mendel observed that in the F2 generation, there were combinations of traits that were not found in the original parental (P) generation, such as plants with green round seeds or yellow wrinkled seeds. These new combinations occurred due to the principles of genetic inheritance that Mendel would later define as segregation and independent assortment. The offspring with trait combinations not observed in the P generation are known as recombinants.
