Variation, a part of genetics, means the degree by which progeny differ from their parents. One of the causes of variation is hidden in _______.
Sexual reproduction involves the fusion of gametes which contains DNA from two different parents and leads to the formation of unique progeny that is different from them.
Variations is the degree by which the progeny differs from the parents. Sexual reproduction involves mixing of genes from the two parents to produce an offspring. Hence, sexual reproduction is a hidden cause of variation.
This is not possible in asexual reproduction as only one parent is involved in the production of offspring.
Vegetative propogation is a kind of asexual reproduction where a part of a plant gives rise to a new plant.
Parthenogenesis is the production of offspring from unfertilised eggs which implies that the genetic material present in the offspring will be from one parent.
