A round seeded plant is crossed with a wrinkled seeded pea plant and all plants in the F1 generation were round
a. Which is the dominant trait and why?
b. If the F1 plants were allowed to self fertilise what would be the expected phenotypic and genotypic ratio in the F2 generation?
c. What law was based on this cross?
d. If the F1 plant was crossed with a wrinkled plant what would be the expected phenotypic and genotypic ratio in the F2 generation
e. What type of cross is this?
Please help me with this question.

Answer:
Two alleles for a given gene in a diploid organism are expressed and interact to produce physical characteristics. The observable traits expressed by an organism are referred to as its phenotype. An organism’s underlying genetic makeup, consisting of both the physically visible and the non-expressed alleles, is called its genotype. Mendel’s hybridization experiments demonstrate the difference between phenotype and genotype. For example, the phenotypes that Mendel observed in his crosses between pea plants with differing traits are connected to the diploid genotypes of the plants in the P, F1, and F2 generations. We will use a second trait that Mendel investigated, seed color, as an example. Seed color is governed by a single gene with two alleles.
