Seven
What did Mendel focus on when selecting traits for his experiments with pea plants?
Traits that existed in two easily distinguishable forms
Which terminology was NOT known to Mendel during his experiments with pea plants?
DNA
What term is now used to refer to the genetic factors that Mendel described in his pea plant experiments?
Alleles
According to Mendel's First Law of Segregation, how many alleles does an individual diploid organism possess for any particular characteristic?
Two
What happens when two alleles of an individual plant separate into gametes?
One allele goes into each gamete
In Mendel's monohybrid crosses, what was the reason behind some traits disappearing in the F1 heterozygous offspring?
Presence of recessive alleles only
What did Mendel do to ensure that each plant was pure breeding for the traits he chose to study?
Monitored the plants for two generations.
In Mendel's monohybrid crosses, what ratio of traits emerged in the F2 generation?

What was the outcome when Mendel crossed a pea plant with round seeds with one that had wrinkled seeds in the parental generation?
All F1 seeds were round.
What did Mendel observe when he conducted reciprocal crosses in his pea plant experiments?
The results were the same.
Learn about Gregor Mendel's groundbreaking experiments with pea plants in the 19th century, which laid the foundation for the field of genetics. Discover how Mendel's use of pea plants allowed him to observe hereditary traits and establish the principles of inheritance.
