QUESTIONS AND VERIFIED ANSWERS


Mendel was able to study seven traits in all the pea
plants in each generation. Which of his hypotheses
allowed him to analyze each trait separately?
Wrong. For each inherited trait, there is only one copy of
the gene that codes for that trait.
If a scientist wanted to follow Mendel's experiment
with a different kind of plant, which type of plant
would she examine?
A plant that has only two alleles for a trait.
What controls traits and inheritance?
nucleic acids
Some people have freckles, and some people do not
have freckles. If a child has freckles, at least one
parent has freckles. However, the child may have a
sibling that does not have freckles. Which statement
best describes the presence of freckles?
There are two alleles for freckles.
If Mendel had crossed a true breeding dominant plant
with a true breeding recessive plant, in which of the
three generations is the recessive trait visible?
P generation and F2 generation
Which is the best example of a hypothesis leading to
new experimental methods?
Thomas Hunt Morgan continued the genetic research of
Gregor Mendel, but Morgan used fruit flies.
