Why would a pea plant that is heterozygous for plant height of the dominant phenotype?

Question: Why would a pea plant that is heterozygous for plant height have the dominant phenotype? It has one dominant and one recessive allele, so the phenotype is mixed. It has one dominant allele, which, by definition, would be expressed in the phenotype.

What is the phenotype of a pea plant with a heterozygous genotype for height here tallness is the dominant trait group of answer choices?

Each parent only donates one allele for each gene to an offspring. For example, remember that for the height gene in pea plants there are two possible factors. These factors are alleles. There is a dominant allele for tallness (T) and a recessive allele for shortness (t).

What is the phenotype of a heterozygous dominant?

The genotype gives rise to the phenotype. Depending on the different relationships between alleles, different phenotypes are created in a heterozygous individual. In alleles that show complete dominance, the heterozygous phenotype will be the same as the dominant phenotype.

Is tallness a dominant trait in pea plant?

For the height of a plant, there can be two traits – tall and dwarf. Tallness is a dominant trait and dwarfism is a recessive trait.

What alleles represent a pea plant that is heterozygous for tallness?

The “TT” and “Tt” crosses both have at least one “T” allele, so they are tall plants.

What trait in pea plants is being studied in the cross above what are the two alleles of this trait?

Terms in this set (6) What trait in pea plants is being studied in the cross shown above? The trait that is being studied is the height of the pea plants. What are the two alleles for this trait. Which allele is the dominate alleles for this trait?

What is the genotype of a heterozygous pea plant?

Heterozygous means that an organism has two different alleles of a gene. For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). People with CF are homozygous recessive.

When a heterozygote has an intermediate phenotype?

This type of relationship between alleles, with a heterozygote phenotype intermediate between the two homozygote phenotypes, is called incomplete dominance.

How would geneticists represent the genotype of a homozygous tall pea plant?

For example, in pea plants, height is governed by a single gene with two alleles, in which the tall allele (T) is dominant and the short allele (t) is recessive. A true-breeding tall pea plant would have the genotype with two dominant alleles, usually represented as TT .

What is a cross involving two traits?

Dihybrid cross is a cross between two individuals who differ in two observed traits that are controlled by two distinct genes.
