Is a trait for tallness in pea plants. The trait for shortness is. In a case of simple dominance what is the height of a plant with the genotype?
In pea plants, the trait for tallness is typically dominant, while the trait for shortness is recessive. In a case of simple dominance, a plant with a genotype that includes at least one dominant allele for tallness (e.g., TT or Tt) will be tall. Conversely, only a plant with the homozygous recessive genotype (tt) will be short. Thus, a plant with the genotype TT or Tt will be tall.
What is a genetic factor that is blocked by the presence of a dominant factor?
A genetic factor that is blocked by the presence of a dominant factor is known as a recessive allele. In a heterozygous genotype, where one allele is dominant and the other is recessive, the dominant allele's traits will be expressed while the recessive allele's traits are masked. For example, in pea plants, the allele for tall stems (dominant) will override the allele for short stems (recessive), resulting in all offspring displaying the tall phenotype.
What is the white parent's genotype?
To determine a white parent's genotype, we first need to know the trait being analyzed, such as skin color or flower color in plants. Generally, in genetics, "white" can indicate a homozygous recessive genotype (e.g., "aa") if it is a recessive trait. However, if "white" is a dominant trait, the genotype could be homozygous dominant (e.g., "AA") or heterozygous (e.g., "Aa"). Therefore, more context about the specific trait and its inheritance pattern is needed to accurately define the genotype.
What is the meaning for Alleles tt?
In genetics, "tt" represents a homozygous recessive genotype for a specific trait, where both alleles for that trait are recessive. This means that the individual will express the recessive phenotype associated with that trait, as there are no dominant alleles present to mask the effect. For example, if "t" represents a trait for short height in plants, a plant with the genotype "tt" would be short.
In a genotype plant height such as Tt what does each letter represent?
In the genotype Tt, each letter represents an allele for a specific trait—in this case, plant height. The capital letter "T" typically denotes the dominant allele, which may result in tall plants, while the lowercase letter "t" signifies the recessive allele, associated with shorter plants. Therefore, the plant with the genotype Tt has one dominant allele and one recessive allele, likely resulting in a tall phenotype due to the dominance of the "T" allele.

What size pea plants would result when two short plants are crossed?
It depends on whether the short trait is dominant or recessive. If shortness is dominant, the resulting pea plants would be of intermediate height. If shortness is recessive, the resulting pea plants would be short like the parents.
In a genotype plant height such as Tt what does each letter represent?
In the genotype Tt, each letter represents an allele for a specific trait—in this case, plant height. The capital letter "T" typically denotes the dominant allele, which may result in tall plants, while the lowercase letter "t" signifies the recessive allele, associated with shorter plants. Therefore, the plant with the genotype Tt has one dominant allele and one recessive allele, likely resulting in a tall phenotype due to the dominance of the "T" allele.
Pure breeding long stem and pure breeding short stem pee plants are crossed According to Mendel's laws of heridity what will the f2 generation be?
Allele for tall stem (dominant)- T Allele for short stem (recessive)- t The F1 generation would all be tall-stemmed plants with the genotype Tt (heterozygous). The F2 generation would consist of: 25% Tall plants with the genotype TT (homozygous dominant) 50% Tall plants with the genotype Tt (heterozygous) 25% Short plants with the genotype tt (homozygous recessive)
What does a homozygous recessive trait look like?
A homozygous recessive trait manifests when an organism carries two identical recessive alleles for a particular gene. This means that both copies of the gene are the same and express the recessive phenotype, which often appears when the dominant allele is absent. For example, in pea plants, if the allele for green seeds (dominant) is represented as "G" and the allele for yellow seeds (recessive) as "g," a homozygous recessive plant would have the genotype "gg" and display yellow seeds.
One of the traits that Mendel studied was pod shape in pea plants If a full pod F is dominant and a flat pod f is recessive what is the genotype of plants with flat pods?
They wouldhave to be f-f - otherwise they would surely have full pods as the full pod (F) is dominant. F-F would result in full pods, F-f likewise would result in full pods as F is dominant and f is recessive. The only combination that would result in flat pods is therefore f-f.
How are dominant and recessive traits represented?
Autosomal recessive alleles ( both males and females) and X-linked alleles in females always express themselves in homozygous condition. On other hand, X -chromosome linked recessive allele express singly in males.
An organism with a genotype of Hh is a hybrid because?
an organism with a genotype of Hh is a hybrid because it carries two different alleles for a particular trait. In this case, Hh represents a heterozygous genotype, indicating that the organism inherited different alleles from each parent for that specific gene.
