What does pure dominant mean?
"Pure dominant" refers to a genetic trait that is consistently expressed when a specific allele is present in an individual's genotype. In inheritance patterns, a pure dominant trait will mask the presence of any recessive alleles in the same gene.
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?
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.
What is pure breeding in genetics and how does it impact the inheritance of traits in organisms?
Pure breeding in genetics refers to the process of breeding individuals that have the same genetic makeup for a particular trait over multiple generations. This results in offspring that consistently exhibit the same trait as the parents. Pure breeding impacts the inheritance of traits by ensuring that specific traits are passed down consistently from one generation to the next, leading to predictable outcomes in offspring.
What does it mean if a trait or allele is resevive?
A recessive trait or allele is one that is only expressed when an individual has two copies of it, one inherited from each parent. In the presence of a dominant allele, the recessive allele's expression is masked.
What does pure dominant mean?

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.
The appearance of a recessive trait in offspring of animals most probably indicates that?
both parents carry a copy of the recessive allele for that trait. This means that the offspring inherits two copies of the recessive allele, expressing the trait. If both parents were carriers of the recessive allele, there is a 25% chance of the offspring inheriting two copies and showing the trait.
What does Catina mean?

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.
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.
What does ancestral trait mean?
a ancestral trait is a distinguishing feature that has been past on from a ancestor
What is the genotype of pure lines?
The genotype of pure lines refers to individuals that are homozygous for a particular trait, meaning they carry the same alleles for that trait. For example, in a pure line of plants, all individuals would have the same genotype for a specific gene, such as AA or aa. This genetic uniformity is desired in breeding and research to study the effects of specific alleles.
What are character traits that Sam represents from lord of the rings with examples showing the trait?
brave, pure, considerate
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 inherited trait mean?
An inherited trait is a feature or characteristic of an organism that has been passed on to it in its genes.
