Mendel described two seed shapes among the pea seeds in his study: Smooth and Wrinkled.
Seeds come in different sizes and shapes. Some are oval with a point at one end. This would be an example of an apple seed. Other seeds are helicopters which means they spin when dropped. An example of this seed is a conifer tree seed.
The plant is most likely a homozygous dominant plant for seed shape, meaning it contains two dominant alleles for round seed shape (RR). This allows for consistent expression of the round seed trait in offspring.
Yes, in Mendelian genetics, the round seed shape trait is typically dominant over the wrinkled seed shape trait.

Both parent plants had the round seed shape phenotype, as the round seed shape (Capital R) is dominant over the wrinkled shape (lowercase r) in Mendel's observations. This means that both parent plants must have had at least one dominant allele (Capital R) for round seed shape.
because of the seed ,it forms into a round shape.
Mendel referred to the trait that appeared in all first-generation plants as the "dominant" trait. In his experiments with pea plants, he observed that certain traits, such as flower color or seed shape, consistently overshadowed others in the offspring. The traits that did not appear in the first generation were termed "recessive." Mendel's work laid the foundation for the principles of heredity and genetics.
Mendel observed round and oval seed shapes.
Many organisms contain two copies of each chromosome, and generally these two chromosomes are not identical. If a particular trait, such as the shape of a pea, is determined by one particular section of a chromosome, it is possible for the two copies of the chromosome to have different instructions for the trait. If the two sections of the two chromosomes have different instructions, this is called being heterozygous.Often if an organism is heterozygous for a trait, one of the sets of instructions (called an allele) will be dominant over the other. This means that if either of the chromosomes has that dominant version of the allele, that is the set of instructions that will be followed.Examples: The gene for seed shape in pea plants exists in two forms, one form or allele for round seed shape (R) and the other for wrinkled seed shape (r). A heterozygous plant would contain the following alleles for seed shape: (Rr).Organisms have two alleles for each trait. When the alleles of a pair are heterozygous, one is dominant and the other is recessive. Using the previous example, round seed shape (R) is dominant and wrinkled seed shape (r) is recessive. Round: (RR) or (Rr), Wrinkled: (rr).
Round (smooth) and wrinkled
Mendel used pea plants to explain heredity and trace the inheritance of traits such as seed color, seed shape, and plant height. His experiments laid the foundation for modern genetics and our understanding of how traits are passed from one generation to the next.
