Cells have DNA just to make and run that particular cell
Every body cell has identical DNA
The DNA changes continuously

The DNA is identical
The offspring's DNA will be a mix of the parent and their siblings
The offspring's DNA will be double the parent's DNA

a mathematical model
a computer model
a visual model
a physical model
Which of the following is an advantage of asexual reproduction?
The offspring are genetically identical
The offspring have genetic diversity
It takes longer than sexual reproduction

How are traits inherited in sexual reproduction?
Males get their traits from the father, females get their traits from their mother
Offspring get their traits from their mother only
Offspring get half of their traits from each parent
Offspring get new traits- it doesn't matter what traits their parents have.
