In pea plants, individuals that are heterozygous (Pp) for a particular allele exhibit a phenotype influenced by both the dominant (P) and recessive (p) alleles. The dominant allele typically masks the effect of the recessive allele, resulting in the dominant trait being expressed. For example, if P represents purple flowers and p represents white flowers, Pp plants will display purple flowers. This demonstrates the principles of Mendelian inheritance where dominant traits prevail in heterozygous conditions.
In pea plants, individuals that are Pp for the alleles that code for flower color will have purple flowers. What is the phenotype?
True breeding pea plants for height typically exhibit homozygous alleles, meaning they have two identical alleles for the trait. For height, this could be represented as either "TT" for tall plants or "tt" for short plants, where "T" is the dominant allele for tallness and "t" is the recessive allele for shortness. Therefore, the two allele combinations for two true breeding individuals would be "TT" and "tt".
Dominant Allele
When Mendel bred green pea plants with yellow pea plants and all the offspring were yellow, it indicated that the yellow trait is dominant over the green trait. This means that the yellow allele masks the expression of the green allele in the offspring. As a result, even though the green allele is present, it does not manifest in the phenotype of the plants. This observation was crucial in understanding the basic principles of inheritance.
An allele is a gene. It is one form of a gene. For example, height in pea plants is controlled by one gene with two forms. A pea plant can be tall or short. There is a short allele and a tall allele for the gene governing height.

you guys suck
TT or Tt
A+ purple flowers.

In pea plants, the presence of an allele for purple flowers is dominant over the allele for white flowers. This means that if a plant has at least one allele for purple flowers, it will exhibit purple flowers, masking the effect of the recessive white flower allele. As a result, only plants with two recessive alleles will display white flowers. This illustrates the principles of Mendelian inheritance and dominance.
