Mendel prevented self-pollination by the pea plants by removing the pollen-bearing part of the plant.
<h3>Mendel's Experiment</h3>
Mendel conducted several plant breeding experiments to study how traits are inherited in living organisms using the pea plant.
In some of the experiments, he needed the plant not to self-fertilize. Thus, he decided to remove the polling-bearing part of such plants.
The pollen-bearing part of a plant is known as the anther. By doing so, the male gamete, which is the pollen, will not be available to fertilize the female gamete of the same plant.

Answer:
8 genetically different types of gametes.
Explanation:
This is typical heterozygotic trihybrid individual i.e. an individual with three pairs of contrasting characters possessing different alleles on each gene. This is similar to Mendel's observation of F1 hybrid.
According to Mendel's law of independent assortment, the alleles get sorted into gametes independently of one another. Hence, this hybrid (AaBbCc) with three unlinked genes produces 8 genetically different gametes after undergoing meosis viz:
ABC, ABc, AbC, Abc, aBC, aBc, abC, and abc.
The number of gametes formed by this trihybrid heterozygote (AaBbCc) is determined by the formula 2^n, where n represents the number of characters.
Since this is a trihybrid cell involving three unlinked genes, 2^3 = 8
i.e. 8 gametes will be produced as stated earlier.
