Ressive genes. Smooth seeds are dominant in the pea plants Mendel used in his experiments.
A pea plant with wrinkled seeds must have two recessive alleles for the wrinkled seed trait (rr). This means that both of its parents must have contributed a copy of the recessive allele for the plant to exhibit wrinkled seeds.
Suppose that, in a pea plant, round seeds are dominant over wrinkled seeds in the "texture" gene. If you were to take two plants heterozygous for the texture gene and cross them together to make eight new plants, how many of those plants should express the smooth phenotype? Use a Punnett's Square to determine the results.
He allowed plants whose seeds were round or wrinkled in shape to self pollinate. This trait has two variations-either round or wrinkled seeds.
Mendel described two seed shapes among the pea seeds in his study: Smooth and Wrinkled.

In pea plants round seeds are dominant to wrinkled. So to have round seeds you either will have two dominant alleles (homozygous dominant) or one dominant and one recessive allele (heterozygous)
The wrinkled seed is a round cell but has the ressivienie wrinkled seed in it.

The probability that an offspring will have wrinkled seeds is 2 in 4 or 50%
The dominant alleles in Mendel's pea plants were those responsible for the traits of round seeds (R) versus wrinkled seeds (r), yellow seeds (Y) versus green seeds (y), purple flowers (P) versus white flowers (p), and inflated pods (I) versus constricted pods (i).
The wrinkled phenotype of pea seeds is due to a mutation in the gene that encodes for the starch-branching enzyme known as SBEI. This mutation causes a deficiency in the enzyme, resulting in the accumulation of unbranched starch in the seeds, which leads to the wrinkled appearance.

Round and wrinkled seeds were observed by Mendel in Pea plant while experimenting on its hybridization process. Round or wrinkled stage of seed is a physical trait in pea plant.
He allowed plants whose seeds were round or wrinkled in shape to self pollinate. This trait has two variations-either round or wrinkled seeds.
