What did Gregor Johann Mendel study?
Genetics and heredity
What was the focus of Mendel's experiments with garden pea plants?
Analyzing hereditary traits
What was the outcome of Mendel's work around year 1900?
His conclusions were confirmed by others
What was developed in the early 1900s by Sutton and Boveri?
Chromosomal theory of heredity
Which characteristic did Mendel term as dominant in his experiments?
$F1$ phenotype traits
What did Mendel draw conclusions about from his monohybrid crosses?
$F1$ plants inherit genetic factors from both parents
What is the concept or law that states when two different alleles are present in a genotype, only the trait encoded by one of them—the dominant allele—is observed in the $F1$ phenotype?
The Law of Dominance
What did Mendel term as recessive in his experiments?
Traits that disappeared in the $F1$ heterozygous offspring

What was the primary method used by Mendel in his experiments?
Adopting an experimental approach and conducting crosses
What was the significance of Mendel interpreting his results using mathematics?
It enabled him to keep careful records of progeny and compute ratios
Why were garden pea plants suitable for Mendel's experiments?
They were self-fertilizing and produced many offspring
What did Mendel term as dominant and recessive traits?
Dominant traits appeared unchanged in F1 heterozygous offspring
What conclusion did Mendel draw from the results of his monohybrid crosses?
Each plant possesses only one genetic factor encoding a characteristic
What is the Concept or Law of Dominance according to Mendel's experiments?
The dominant allele is always observed in the F1 phenotype
What was the significance of Mendel conducting monohybrid crosses?
It enabled him to study the inheritance of a single characteristic at a time
What led to Mendel's work being unappreciated for about 34 years after it was published?
Lack of understanding and acceptance of his groundbreaking conclusions
How did Mendel's experiments differ from earlier investigators?
Adopted an experimental approach and conducted crosses based on initial hypotheses.
Why did Mendel use garden pea plants for his experiments?
Because they were known to differ in detectably distinct characters.
