Facilitation Questions
Did any of the children inherit a trait from a grandparent? Y es,
all traits inherited by
the children were also traits of the grandparents, but no child’s traits were identical
to all of the traits of one grandparent or parent.
Did any of the children lack one of the grandparents’
traits?
It is very
possible
that the offspring lack one of the grandparent’s traits. The offspring are diverse
because the traits were chosen at random.
How does this compare to traits that you have
inherited from your parents or
grandparents? This was a simplified study of how traits can be tracked through a
family tree, but humans, as well as other organisms, have
many more traits.
Some
of our traits are inherited from our fathers and some of our traits are inherited from
our mothers.
