To determine which alleles are recessive in the seed phenotype, you would need to compare the phenotype of the plants with known dominant phenotypes. Typically, if a phenotype appears in a generation that resembles the parents but differs from the dominant traits, those traits associated with the appearance of phenotype "a" are likely recessive. Observing the inheritance patterns in subsequent generations can further clarify which alleles are recessive based on the phenotypes that re-emerge when homozygous recessive individuals are bred.
When F1 pea plants are allowed to self-pollinate, the phenotype will exhibit a 3:1 ratio in the F2 generation according to Mendel's laws of inheritance. This ratio includes three plants with the dominant trait (e.g., yellow seeds) and one plant with the recessive trait (e.g., green seeds).
Yes. Selective breeding is also used to improve or otherwise change breeds of dogs, cats, horses, cows, and so forth.
The incomplete dominance and codominance involve more than one gene for a particular phenotype, hence the quality of the breed remains static in plants as well as in animals.
What percentage of the possible types of offspring had the same phenotype as the parents
The genotype of the offspring that had the same phenotype as the parents is rr or wrinkled. The phenotype for the seed shape of both parent plants is round.
The phenotype of offspring plants refers to their observable traits, such as their physical appearance, behavior, or other characteristics. These traits result from the interaction between the plant's genetic makeup (genotype) and environmental factors. Offspring plants may exhibit a combination of traits inherited from their parents, leading to variations in their phenotype.

Nope! TT is the dominant phenotype (what ever it may be) and tt is the recessive phenotype (what ever that may be).So say T is the allele for Tall plants, t is the allele for short plants. TT would be show the tall phenotype while tt would show the short phenotype. If the genotype was Tt, the phenotype would be tall as well because the T is dominant and masks the phenotype of t (short plants).
