The trait for tallness in pea plants is an example of a dominant trait. In Gregor Mendel's experiments with pea plants, he found that the tall phenotype (T) is dominant over the short phenotype (t). This means that a plant with at least one tall allele (T) will exhibit the tall phenotype, while only those with two recessive alleles (tt) will be short. Thus, tallness is expressed more frequently in the population when both traits are present.
This was an example of tallness being a dominant phenotypic trait in pea plants
The first human trait shown to be inherited by Mendelian rules was eye color, as demonstrated by Gregor Mendel in his experiments with pea plants. He found that eye color followed simple dominant and recessive inheritance patterns.
When Mendel bred green pea plants with yellow pea plants and all the offspring were yellow, it indicated that the yellow trait is dominant over the green trait. This means that the yellow allele masks the expression of the green allele in the offspring. As a result, even though the green allele is present, it does not manifest in the phenotype of the plants. This observation was crucial in understanding the basic principles of inheritance.
The first generation of of pea plants that Mendel bred were tall.

True-breeding pea plants always produce offspring with the same traits as the parent plant. This is because they are homozygous for the trait of interest, resulting in consistent expression in the offspring generation.
If green pea pods are dominant over yellow pea pods, all offspring from the cross will have green pea pods. This is because the dominant trait (green) will mask the recessive trait (yellow) in the heterozygous offspring. The genotype of the offspring will be heterozygous for the pod color trait.

In pea plants the tallness trait moving separately from the color trait is an example of Mendel's 2nd law of Independent assortment. It states the appearance of one gene will not affect the appearance of another gene.
It suggests that Rachel's pea plants displayed incomplete dominance or codominance, where alleles for the flower color trait interact in a way that results in a blending or combination of both parental traits in the offspring.
