Aspecies has a diploid number of 36. without meiosis, the gametes would each contain chromosomes, and the fertilized ovum would have chromosomes.

A Species has a diploid number of 36.  Whithout meiosis, the gametes would each contain  36 chromosomes, and the fertilized ovum would have 72 chromosomes.

Explanation:

Dipliod cell contain a normal count of chromosomes.  The meiosis is the reproduction and division of the sexual cell (called gametes). when a cell comes in meiosis, at the end of the meiosis has 18 chromosomes (half of the total of chromosomes and it´s called haploid).      A ovum and a spermatozoon are gametes, so they have 18 chromosomes each.  When fertilization happens, the chromosomes add up, so there are 36

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.
