Conception,
or fertilisation, is the point at which a new
organism begins it's life.
...in other words, this is the point at which
the sperm cell meets the egg cell.
The "sex" of the sperm cell determines the sex of the baby.
XX = female
XY = male
Ovulation & Conception
Ovulation is the point in a female's
menstrual cycle when a mature ovum is released from the ovary, pushed down the fallopian tube, and is available to be fertilized.
Ovum
moment of conception
exponentialcell division
(mitosis)
sperm completes entry
into ovum (egg) and now
becomes a zygote
zygote enters uterus
Implantation is when the zygote attaches itself to the endometrium (uterine lining) and begins rapid cell division, or mitosis. 9 months later, the stork drops by for a visit!
