Answer:
PARTHENOGENESUS (parthenos = virgin, genesis =produce)
Explanation:
Development of an egg into a complete individual without fertilization is known as parthenogenesus. it was first discovered by charles bonnet in 1745.
Parthenogenesus can be classified into two major types namley ,artificial and natural parthenogenesus .
Natural Parthenogenesus :
parthenogenesus occur regularly,constantly and naturally.
natural Parthenogenesus can be different type :
Arrhenotoky : only male produced by this type.
i.e : Honeybee.
Thelytoky: only females can be produced.
i.e : Solenobia.
Amphitoky: egg can develop into any sex.
i.e : Aphis.
Natural Parthenogenesus can be to types :
Complete parthenogenesus and incomplete parhenogenesus
Artificial Parthenogenesus :
the unfertilized egg develop into complete individual by physical or chemical stumuli.
i.e : Annelid and seaurchin egg
