a homozygous
It would depend on if the dominant genes are the same or different. Say the dominant alleles were different. In this case, they are co-dominant. If they are the same and both dominant homosytus.
hh X Hh You get two recessives; hh and hh and two heterozygous plants; Hh and Hh
Two recessive alleles can not take over a dominant allele because there are only two alleles in a pair. This can only happen if there is a mutation because the dominant always takes over the recessive.
If a plant is homozygous tall then it would possess two tall genes instead of a short gene. If for the notation you use B to represent the dominant tall gene and b to represent the recessive short gene the plant would carry and "BB" compliment of genes.
Recessive genes. These genes are only observed when an individual inherits two copies of the recessive allele.
Garh! They be called "heterozygous" matey. Arrr! Animals can also be heterozygous, ye landlubber!

The weaker of two genes is called the recessive gene. In the presence of a dominant gene, the recessive gene is not expressed in the organism's phenotype.
Pure TraitsPure traits can be either recessive or dominant. Pure traits may have two dominant genes or two recessive genes. For example, a pea plant may have two genes for tallness, which is dominant trait in pea plants. This plant is homozygous plant with a pure dominant trait for tallness. All of the offspring from this plant will be tall. A pea plant with two genes for shortness is also a pure organism. However, shortness in pea plants is a recessive trait. This plant is a homozygous plant with a pure recessive trait for height. The offspring from this plant will be short if it pollinates with another plant that has two genes for shortness. If this plant pollinates with a tall pea plant, the tall dominant gene will mask or cover up the recessive gene for shortness. Both plants are homozygous or pure plants; one is a pure dominant pea plant, the other is a pure recessive pea plant.Hybrid TraitOrganisms that have two unlike genes for a certain trait are called hybrid. A pea plant with one recessive gene for shortness and one dominant gene for tallness is a hybrid for that trait. A hybrid is called heterozygous, as it has two different alleles. The offspring from a pure tall pea plant, cross-pollinated with a pure short pea plant, will result in a heterozygous plant for tallness. No organism has all dominant or all recessive genes. An organism may be pure in certain traits and hybrid others. Remember, that a dominant trait in one kind of organism may be a recessive trait in another organism.
A pea plant with two tall genes is called a homozygous tall plant.
Homozygous dominant for two dominant genes or homozygous recessive for two recessive genes.
A pure tall plant refers to one that has been consistently bred with other tall plants of the same variety to maintain its tall characteristics. A hybrid tall plant, on the other hand, results from cross-breeding two different varieties of plants to create a new plant with varying characteristics, such as height.

Each gene has two alleles. When an allele is dominant, it will express the phenotype of that allele. Recessive alleles are only expressed when there are two copies of that allele. Edited answer: Only those genes are called dominant which show their phenotypic expression in an individual.
