What would be the consequences if there is no meiosis in organisms that reproduce sexually?

Explanation

(1) If meiosis did not occur, fusion of gametes would result in a doubling of the chromosomes for each successive reproduced generation.
(2) For example, in case of man egg cell and sperm cells like other must contain 46 chromosomes.

(3) This results in formation of abnormalities in each generation.
(4) If meiosis did not occur, there is no genetic variation in the offsprings produced by random fusion of the gametes.
(5) New characters will not appear in the off springs.
(6) The process of evolution will be stopped.
