To be pure for a specific trait means that both of the alleles that comprise that trait are both dominant alleles.

What does pure dominant mean?
Pure dominant = two dominant genes that make a "pure dominant" trait. Pure Recessive = two recessive genes that make a "pure recessive" trait.
What did mendel find in the f1 generation?
he crossed two pure lines
What is the difference between a Pure tall plant and hybrid tall plant?
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.
What does it mean if a trait or allele is resevive?
It is the non dominant trait. You would have to have 2 recessive to have that trait but you only need one dominanr=t to have that trait
What does it mean if there are 2 different alleles for a trait?
A Trait Could Show Up In Two Different Forms
What does pure dominant mean?
Pure dominant = two dominant genes that make a "pure dominant" trait. Pure Recessive = two recessive genes that make a "pure recessive" trait.
What did mendel find in the f1 generation?
he crossed two pure lines
What is arecessive trait?
i mean to say what is a recessive trait not what is recessive trait sorry
What does being heterozygous for a trait mean?
the 2 alleles of the gene for the trait are different on the 2 homologous chromosomesBeing heterozygous for a trait means that they have different alleles for a trait. For instance: Tt would be heterozygous and TT or tt would be homozygous because they are both eitehr little or big t's.it mean the gene is not pure or for example suppose a person is blood group A but actually he is having A and O; because O is recessive trait the gene express the A trait instead, making the person having blood group A.
The appearance of a recessive trait in offspring of animals most probably indicates that?
one parent was pure dominant and one parent was pure recesive .
What is the definition for the word characteristics?
Charateristics is a trait for example a mean trait
Is a gene a genotype that is not mixed?
No. A gene is a part of the DNA that identifies the outcome of a certain trait or part of a trait. A genotype is the actual definition of the gene for each individual.
What is the difference between a Pure tall plant and hybrid tall plant?
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.

What does the French word 'trait' mean?
The French word 'trait' means dash, line, or stroke. It also may mean feature, or [personality] trait. And it may mean dart or shaft, and even trace.
What does it mean if a trait or allele is resevive?
It is the non dominant trait. You would have to have 2 recessive to have that trait but you only need one dominanr=t to have that trait

What does it mean when a trait is recessive?
The principle of excessiveness is defined as the explanation of why one trait will not show over another. If a trait is recessive it will not show when a dominant trait is present.
