B. Plants and animals can both reproduce sexually.

Explanation:

In addition to studying several phenotypic characteristics of the pea in isolation, Mendel also studied the combined transmission of two or more characteristics. In one of his experiments, for example, the color of the seed, which can be yellow or green, and the texture of the seed husk, which can be smooth or rough, were considered simultaneously. In this way Mendel studied independent assortment, he used as evidence the animals' ability to reproduce sexually.

Plants originating from yellow and smooth seeds, both dominant traits, were crossed with plants originating from green and rough seeds, recessive traits. All seeds produced in the F1 generation were yellow and smooth.

The F2 generation, obtained by the self-fertilization of plants originating from F1 seeds, was composed of four types of seeds: 9/16 yellow-smooth, 3/16 yellow-rough, 3/16 green-smooth, 1/16 green-rough.

Mendel concluded that independent factor segregation for two or more characteristics was a general principle, constituting a second law of inheritance. Thus, he called this principle the second law of inheritance or the law of independent segregation, later called Mendel's second law: The factors for two or more characteristics are segregated in the hybrid, being distributed independently to the gametes, where they combine at random.
