How was Mendel able to determine that certain traits were dominant and some were recessive?

Gregor Mendel was able to determine traits by the ratio in which they appeared. For instance, he determined that a recessive trait will show up 25 percent of the time if one parent has it.

Mendel crossed pea plants with contrasting traits and observed the offspring. He found that one trait (dominant) masked the expression of the other (recessive) in the first generation. By allowing the plants to self-fertilize over multiple generations, he determined the patterns of inheritance and identified the ratios of dominant to recessive traits in the offspring.

What did Mendel mean by a dominant factor?
Mendel meant that a dominant factor is a gene that expresses its trait in an individual when present with the corresponding recessive gene. The dominant allele masks the expression of the recessive allele in a heterozygous individual.
In the F2 generation in Mendel's experiment's the ratio of dominant to recessive traits was?
The ratio of dominant to recessive traits in the F2 generation of Mendel's experiments was 3:1. This is known as the phenotypic ratio for a monohybrid cross, where three individuals display the dominant trait for every one individual displaying the recessive trait.
What are the states that some alleles are dominant and others are recessive?
Mendel's law of inheritance.
What is mendels ratio for dominant to recessive traits?
its 3:1
In which generation were recessive traits visible Mendel's experiments?
Recessive traits were visible in the F2 generation of Mendel's experiments, where the offspring of the F1 generation showed a 3:1 ratio of dominant to recessive traits.
What did Mendel mean by a dominant factor?
Mendel meant that a dominant factor is a gene that expresses its trait in an individual when present with the corresponding recessive gene. The dominant allele masks the expression of the recessive allele in a heterozygous individual.
Recessive genes will always be masked by dominant genes This is Mendel's principle of?
This is Mendel's principle of dominance. Dominant alleles will always mask the presence of recessive alleles in a heterozygous genotype.
What ratio did mendel find for dominant to recessive?
3:1
In the F2 generation in Mendel's experiment's the ratio of dominant to recessive traits was?
The ratio of dominant to recessive traits in the F2 generation of Mendel's experiments was 3:1. This is known as the phenotypic ratio for a monohybrid cross, where three individuals display the dominant trait for every one individual displaying the recessive trait.
What did Mendel call the observed trait and the trait that seemed to disappear?
Mendel called the observed trait the dominant trait and the trait that seemed to disappear the recessive trait.
What was the radio of dominant to recessive phenotype in the F2 generation of Mendel's experiment?
The ratio of dominant to recessive phenotype in the F2 generation of Mendel's experiment was 3:1. This means that for every 3 individuals expressing the dominant trait, there was 1 individual expressing the recessive trait.
Gregor Mendel is studied in this course because he?
did research on dominant and recessive traits.
What are the states that some alleles are dominant and others are recessive?
Mendel's law of inheritance.
What is mendels ratio for dominant to recessive traits?
its 3:1
Is it true that mendel assumed that a dominant allele had masked the corresponding recessive allele in the f1 generation?
Yes, Gregor Mendel's principle of dominance stated that in the F1 generation, the dominant allele would mask the expression of the corresponding recessive allele. This means that only the dominant trait would be observed in the offspring.
To describe how traits can disappear and reappear in a certain pattern from generation to generation Mendel proposed?
Mendel proposed the concept of dominant and recessive alleles that determine trait expression in offspring. Through his experiments, he discovered that traits can disappear in one generation due to being masked by dominant alleles, but can reappear in future generations when those recessive alleles are passed down and expressed. This pattern of inheritance is now known as Mendelian genetics.
Who is the scientist that discovered dominant and recessive traits?
Gregor Mendel, an Austrian monk, is credited with discovering dominant and recessive traits through his work with pea plants in the mid-19th century. Mendel's experiments laid the foundation for the field of genetics.
