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.
When plants that are true breeding for different traits of a characteristic are crossed the trait observed in the first generation is called the?
dominant
When plants that are true breeding for different traits of a characteristics are crossed the trait observed in the first generation is called the?
dominant
When plants that are true breeding for different traits of a characteristic are crossed the trait observed in the first generation is called?

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.
What did Mendel call the trait that appeared in all of his first generation plants?
Mendel referred to the trait that appeared in all of his first-generation plants as the "dominant" trait. In his experiments with pea plants, he observed that when he crossed different varieties, one trait would consistently manifest in the offspring, overshadowing the other trait, which he termed "recessive." This foundational concept established the basis for understanding inheritance patterns in genetics.
Trait that shows up generation after generation?
A trait that is consistently passed from parent to offspring through multiple generations is known as a hereditary trait. This trait is typically determined by genes and can be observed in multiple family members over time.
What did Mendel call the observed trait and the trait that seemed to disappear?
he called the observed traits dominant and the disapear traits recessive.
Does a dominant trait appear in the first generation?
Yes, a dominant trait will appear in the first generation if one of the parents carries the dominant allele. Dominant traits only need one copy of the allele to be expressed.
When do you first learn which trait is dominant?
when observing the F1 generation of a monohybrid cross
What kind of trait seems to disappear in the first generation?
all flowers are purple
How did Mendel show that the green-seed trait did not disappear but was only masked?
Mendel demonstrated that the green-seed trait did not disappear but was simply masked by conducting crossbreeding experiments with pea plants. He observed that when he crossed purebred yellow-seed plants with purebred green-seed plants, the first generation (F1) exhibited only yellow seeds. However, when he allowed the F1 generation to self-pollinate, the second generation (F2) revealed a 3:1 ratio of yellow to green seeds, indicating that the green-seed trait was still present but hidden in the F1 generation. This suggested the concept of dominance, where the yellow trait masked the expression of the green trait.
