In one experiment about Pea plants were Mendel cross-pollinated smooth yellow pea plants with the wrinkly green pea plant. The first generation pea crop or f1 was yellow and round as its yellow and round parent. During the cross-pollination the yellow pea parent somehow dominated the green pea plant thus the yellow pea children. This experiment resulted to Mendel discovering the two types of traits-dominant and recessive. For this experiment the dominant trait was yellow and round because they had been the result in the children pea plant. The inheritance of each trait is determined by units or factors now later called as genes. When Mendel tried the experiment again, this time using the result of the parent generation- all yellow and all round and pollinating it with a self pollinated grown up plant(f2). However this time the result was of yellow and green pea crops. Biological inheritance is determined by factors that are passed from one generation to the next.The principle of dominance states that some alleles are dominant and others are recessive. Organisms with dominant allele for a particular form of a trait will always exhibit that form of the trait.
