Answer:
Eggs are fertilised in the fallopian tubes and become implanted in the uterus.
Step-by-step explanation:
The eggs are produced in the ovaries and from the ovaries, the eggs then travel down the tube-like structures known as fallopian tubes, that are connected to the uterus.
It is in these fallopian tubes where the sperms meet the eggs and fertilization occurs, the zygote thus formed then further travels down the fallopian tube and reaches the uterus where the implantation occurs.
