What is characteristic of the F2 generation?

The F2 generation is characterized by offspring that result from a cross between two F1 individuals. Since the F1 generation usually consists of hybrids carrying dominant traits, the F2 generation exhibits a mixture of traits due to the recombination and segregation of alleles. This can lead to the expression of both dominant and recessive traits in various combinations, reflecting the genetic variability inherent in the offspring. As a result, the F2 generation showcases a variety of phenotypes, which may include traits that were not visible in the F1 generation.

In contrast to the options that discuss uniformity or dominant traits, the nature of genetic inheritance involves a blending of traits from the parents, especially when both homozygous and heterozygous traits are involved. The mixing of traits in the F2 generation serves to illustrate the principles of Mendelian genetics, specifically the law of independent assortment.
