Evidence for Evolution_ Period 3
Model #1: Family Characteristics
1.
2. The organisms in the second row that
are connected to the parents by a line
are the children (offsprings)
3.
4. Organisms in the third line is related
to the first line by being the
grandchildren
5. a. All organisms have at least one
identical trait to that of a grandparent
b. The traits get passed on by DNA
making copies and getting passed on
6. a. All of the organisms in the third
generation exhibit one or more traits
that are not shown in the grandparents
b. The new traits are introduced by: 1)
married in individuals and/or 2)
mutations
7. The children share the most traits
with the parents because new traits had
been introduced into the grandchildren
giving them traits not found in the
grandparents
8. The children (line 2) shares the most
DNA with the parents (line 1) because
there is a direct relationship from parent
to children with no new traits
introduced.
9. The parents got their traits from the
DNA of their ancestors
