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.
