The dominant allele
A dominant allele is an allele that will always express itself in a hybrid individual, masking the expression of a recessive allele. This means that if a dominant allele is present, its trait will be visible in the phenotype of the organism.
A hybrid allele is a combination of alleles from two different parents for a specific trait. It can have two different alleles that may interact in various ways to determine the trait expression.
The alleles for a hybrid tall pea plant are represented as Tt, where "T" is the dominant allele for tallness and "t" is the recessive allele for shortness. In this case, the plant has one allele for tallness and one for shortness, resulting in the tall phenotype due to the dominance of the "T" allele.
The probability of inheriting a specific allele in a hybrid plant would be 1/2 or 50%, as each parent contributes one allele and there are two possible alleles for a specific gene. Each offspring has an equal chance of inheriting either allele from the parent.
A hybrid flower could have a genotype that includes a combination of dominant and recessive alleles for certain traits. For example, a hybrid plant may have a genotype like RrYy, indicating it carries one dominant allele for one trait and one recessive allele for another.

an organism that has two different forms of an allele
A recessive phenotype can only be observed when an individual is homozygous recessive for that trait, meaning they have two copies of the recessive allele. This is because in a heterozygous individual, the dominant allele will mask the expression of the recessive allele.
A hybrid flower could have a genotype that includes a combination of dominant and recessive alleles for certain traits. For example, a hybrid plant may have a genotype like RrYy, indicating it carries one dominant allele for one trait and one recessive allele for another.
Gg represents a hybrid genotype, where "G" is one allele and "g" is another allele for a particular gene. In a hybrid, the alleles are different, while a purebred would have two identical alleles (like GG or gg). Therefore, Gg indicates that the organism is heterozygous for that trait.
To determine the percentage of red roses from a cross between a male purebred red rose (homozygous for the red trait) and a female hybrid rose (which may carry one red allele and one allele for another color), we would need to know the specific genetic makeup of the hybrid. If we assume the hybrid is heterozygous (one red allele and one allele for another color), then 50% of the offspring would be expected to be red. However, if the hybrid carries two different alleles, the percentage could vary. Generally, without more specific information, it's safe to estimate that around 50% of the offspring will be red.

In pea plants, the allele for tall stems is typically represented by the uppercase letter "T," while the allele for short stems is represented by the lowercase letter "t." A hybrid tall pea plant, which has one allele for tallness and one for shortness, would be represented as "Tt." This genotype indicates that the plant will exhibit the dominant tall phenotype due to the presence of the dominant "T" allele.
