What is a dominant form of a kind of characteristic carried by a gene?
trait
The kind of trait that is prevented from showing up because of the dominant gene?
the resesive gene
A trait which always appears when it is present is called what kind of trait?
It is called a dominant trait
What kind of mutation is triple x syndrome?
Most cases of triple X syndrome are not inherited so it is not a dominant or recessive trait.
What is the kind of trait that always appeared in the offspring produced in Mendel's first experiment?
Dominant trait
When one trait is said to cancel out another trait what kind of relationship is said to exist?
dominant
What kind of trait is expressed when two different genes from the same trait are present?
It depends on the gene in question, and the type of dominance of the trait.For monogenetic traits (those controlled by a single gene), the dominant trait(s) will be expressed when two different alleles are present.For example, if B leads to black fur and b leads to white fur:Complete dominance would result in a rabbit with Bb having black fur.Incomplete dominance - Bb would result in grey furCodominance - Bb would result in black and white patches/spots/etc.
What kind of trait always appears in the offspring produced in Mendels first experiment?
Dominant
What kind of letter in punnett square stands for a dominant gene?
capital letter
If you have green eyes and both your parents have brown eyes what kind of trait does your parents have?
They both carried the gene for green eyes as a recessive trait.
What is the kind of trait that seemed to appear in the offspring produced in Mendel's first experiment?
A dominant trait appeared in the offspring produced in Mendel's first experiment.
What is the difference between a pure tall plant and a 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.
