an allele
Round seed shape in peas is an example of a trait controlled by a dominant allele because the presence of even one copy of the dominant allele results in the expression of the round seed shape phenotype. This means that individuals with either two dominant alleles (RR) or one dominant and one recessive allele (Rr) will have round seeds, while individuals with two recessive alleles (rr) will have wrinkled seeds.
False. When Mendel allowed heterozygous F1 plants with round yellow seeds to self-pollinate, he found that the F2 generation followed the expected 9:3:3:1 phenotypic ratio. This means that all possible combinations of seed shape (round or wrinkled) and seed color (yellow or green) were observed in the F2 generation in the ratio of 9 round yellow: 3 round green: 3 wrinkled yellow: 1 wrinkled green.
There would be four possible phenotypes: round yellow peas, round green peas, wrinkled yellow peas, and wrinkled green peas. This is due to the different combinations of alleles for seed shape (R for round, r for wrinkled) and seed color (Y for yellow, y for green) that can result from the cross.
Mendel observed a 9:3:3:1 phenotypic ratio in the F2 offspring, where the traits for seed shape and seed color were independently assorted from each other. This suggested that the alleles for seed shape (round/wrinkled) were segregating independently of the alleles for seed color (yellow/green).

Yes, in Mendelian genetics, the round seed shape trait is typically dominant over the wrinkled seed shape trait.
The wrinkled seed is a round cell but has the ressivienie wrinkled seed in it.
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.
Round (smooth) and wrinkled
Mendel described two seed shapes among the pea seeds in his study: Smooth and Wrinkled.
Round seed shape in peas is an example of a trait controlled by a dominant allele because the presence of even one copy of the dominant allele results in the expression of the round seed shape phenotype. This means that individuals with either two dominant alleles (RR) or one dominant and one recessive allele (Rr) will have round seeds, while individuals with two recessive alleles (rr) will have wrinkled seeds.
Mendel conducted experiments by crossbreeding pea plants with different seed shapes, specifically round and wrinkled seeds. He carefully controlled the breeding process, allowing him to observe the inheritance patterns in the offspring. By analyzing the traits of the resulting generations, he discovered that the round seed shape was dominant over the wrinkled shape, leading to foundational principles of genetics.
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.
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.

The phenotypes of pod color in plants, such as peas, can include green and yellow, while seed shape phenotypes can be round or wrinkled. These traits are often used in genetic studies as they are clearly distinguishable and follow Mendelian inheritance patterns. For example, the green pod color is typically dominant over yellow, and the round seed shape is dominant over wrinkled. These characteristics provide insight into the genetic makeup and inheritance patterns of the plants.
