Which of the following statement is not true for a clone?
A clone inherits the age of the donor organism.

A clone may have a different mitochondrial DNA than the donor organism.
A clone's phenotype can be influenced by environmental factors.
In a plant species that reproduces through apomixis, a mutation arises in a somatic cell that confers resistance to a fungal pathogen. What is the likelihood that this resistance trait will be passed on to the offspring?
Low, as somatic mutations are rarely heritable.
High, as apomixis bypasses meiosis and fertilization.
Dependent on whether the mutation is dominant or recessive.
Zero, as apomixis only involves the maternal gametophyte.
