These are similarities between human spems and egg cells:
They both produce gametes which have half the chromosomes of the adult producing them.
They both contain the 23 chromosomes needed for human development.
sperm
chromosome pairing
The male's sperm cell combines with the female egg or ovum; fertilizes it and is the start of embryo formation.
there would be no fertilization, no zygote formation, which in simple language means no pregnancy
Meiosis generates gametes (sperm and eggs cells). The combination of the gametes makes the zygotes. So, the process meiosis produces only half of a zygote.
the formation of sex cells GAMETES: sperm or egg cells Gamete formation: gametogenesis Sperm formation: spermatogenesis Egg formation: oogenesis
female gametes form to the right of the wall of chromosomes, whereas the gametes in males, form to the left and in the middle of the wall. they are similar in the sperm, but unalike in egg
sperm
Male sperm
zygot, fetus formation

The male's sperm cell combines with the female egg or ovum; fertilizes it and is the start of embryo formation.
Meiosis is the process that occurs in the formation of sex cells(sperm & egg)by which the number of chromosomes is reduced by half
sperm
The egg shell is formed withing the hen and although somewhat porous, not enough for sperm to enter. Fertilization takes place between the ovum and sperm prior to the formation of the completed egg.
Menstruation is a process of expulsion of un used egg in female pregnancy is egg got sperm attached and zygote formation fertilization resulting child birth
