A dandelion produces seeds without meiosis or fertillisation. The adult sporophyte forms diploid, rather than haploid, megaspores that develop into ovules containing diploid, rather than haploid nuclei. One of the nuclei in each ovule becomes an egg and develops directly, without fertilisation, into an embryo that is genetically identical to its parent. This type of reproduction is called

Options

A. parthenogenesis, which is a form of apomixis
B. parthenogenesis, which is a form of amphimixis
C. adventive embryony, which is a form of apomixis
D. agamospermy, which is a form of amphimixis.
