Define different type of parthonogenogensis
Answers
Answer:
Types of Parthenogenesis
There are two types of parthenogenesis:
Natural Parthenogenesis
Artificial Parthenogenesis
Natural Parthenogenesis
In certain animals, parthenogenesis occurs naturally in their life cycles. This is known as natural parthenogenesis.
Natural parthenogenesis can be further divided into:
Complete Parthenogenesis
A few insects have no males and no sexual phase. Such organisms depend upon self-reproduction. This is known as complete parthenogenesis.
Incomplete Parthenogenesis
The life cycle of a few insects involves two generations:
Sexual generation
Parthenogenesis generation
In this, the unfertilised eggs produce males and the diploid eggs produce females. This type of parthenogenesis is called partial or incomplete parthenogenesis.
Artificial Parthenogenesis
The fertilised eggs might sometimes develop parthenogenetically by various chemical and physical means. This is known as artificial parthenogenesis.
Physical Means
Temperature induces parthenogenesis in eggs. For eg., parthenogenesis is induced if an egg is transferred from -30 to -10°C.
Parthenogenesis is caused by ultraviolet light.
Electrical shocks cause parthenogenesis.
When an egg is pricked by a needle, the development occurs parthenogenetically.
Chemical Means
The chemicals that are responsible for the parthenogenesis of eggs are:
Chloroform
Urea and Sucrose
Strychnine
Fat solvents
Acids
Chlorides
Explanation:
Answer:
In the insect order Hymenoptera (which includes bees, wasps, and ants), parthenogenesis can take one of three forms: arrhenotoky, thelytoky, and deuterotoky.
