Which type of genetic trait appears in every generation of offspring?
A dominant genetic trait appears in every generation of offspring because only one copy of the dominant allele is needed for the trait to be expressed.
What did mendel call the trait that appeared in all first generation plants?
Mendel referred to the trait that appeared in all first-generation plants as the "dominant" trait. In his experiments with pea plants, he observed that certain traits, such as flower color or seed shape, consistently overshadowed others in the offspring. The traits that did not appear in the first generation were termed "recessive." Mendel's work laid the foundation for the principles of heredity and genetics.
The factor that always expresses itself in the first filial generation?
The dominant factor always expresses itself in the first filial generation, known as the F1 generation. This means it is the trait that is visible in the offspring when one parent has a dominant allele for a particular characteristic.
Explain Mendel's law of independent?
Mendel's Law - The first law of Mendel states that "In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next generation. Offspring that are hybrid for a trait will have only the dominant trait in the phenotype."
Mendel referred to the characteristic that was expressed in the hybrid F1 or first filial generation as?
Mendel referred to the characteristic expressed in the hybrid F1 generation as the dominant trait. This trait masks the expression of the recessive allele in the heterozygous individual.
The observed trait in the first generation?
Dominant trait
The trait observed in the first generation when parents that have different traits are bred?
The trait observed in the first generation when parents with different traits are bred is known as the dominant trait. This trait is expressed in the offspring because it masks the expression of the recessive trait.
How do you know from a pedigree diagram if a trait is dominant or resessive?
If a trait is dominant, it will appear in every generation where at least one parent has the trait. If a trait is recessive, it can skip generations and may appear in offspring of parents without the trait. Dominant traits are usually expressed in every generation, while recessive traits can "hide" and reappear later.
A trait that appears or is expressed in the f1 generation is what?
A trait that appears or is expressed in the F1 generation is considered dominant. Dominant traits will manifest themselves in the offspring when at least one parent carries the dominant allele for that trait.
When do you first learn which trait is dominant?
when observing the F1 generation of a monohybrid cross
What is an autosomal dominant trait?
An autosomal dominant trait is a characteristic that is determined by a dominant gene located on one of the non-sex chromosomes (autosomes). This means that only one copy of the dominant allele is needed for the trait to be expressed in an individual. Autosomal dominant traits will appear in each generation of a family with affected individuals.
Which type of genetic trait appears in every generation of offspring?
A dominant genetic trait appears in every generation of offspring because only one copy of the dominant allele is needed for the trait to be expressed.

What is the kind of trait that seemed to vanish in the offspring produces in Mendel's first experiment?
Mendel's experiments showed the characteristics of genes that express complete dominance--that is, traits where one allele is completely dominant over another, and the recessive allele does not appear in the phenotype at all. Some of the specific traits that Mendel was testing include pea color (yellow or green, with green being completely dominant) pea surface texture (wrinkled or smooth, with smooth being dominant) and flower color (pink and white, with pink being dominant.)
