kn (knolle)
Radical Axis Mutant
Appears to not have epidermal layer. It does have it but it is disrupted by misoriented and abnormal cell division.
Male Sterile Mutant
Entire male organ is messed up.
Least useful for studying
Microsporogenesis Mutant
Microsporogenesis is messed up

3 Kinds of Apoximis (Sexual Reproduction In Plants)
1. Diplospory
2. Apospory
3. Adventitious Embryo
Diplospory
No meiosis of megaspore. Results in 2n egg cell which acts as a zygote
Apospory
2n cell from ovule undergoes sporophyte genesis
Adventitious Embryo
Single cell forms adventitious embryo (2n). Doesn't create embryo sac

Gametic System Self Incompatability
Determined by genotype of male gametophyte
Same allele = no fertilization
Sporophytic System Self Incompatability
Determined by genotype of the sporophyte that gives rise to the pollinating male gametophyte
No alleles can be the same
