questions and answers
Preconception Genetic Testing is an important tool for - correct answer ✔✔ couples whose
genetic makeup might have negative consequences on their children's health
To have a period, the woman must have - correct answer ✔✔ ovum
Cell Division results in - correct answer ✔✔ gametes which are the sex cells = male sperm,
female ovum, each cell contains 23 chromosomes
Gametogenesis (oogenesis) for a female begins during - correct answer ✔✔ fetal development
= girls are born with eggs present within the ovary and remain suspended until puberty
Gametogenesis (Spermatogenesis) for a male occurs in - correct answer ✔✔ the testes once the
male reaches puberty
Conception is the - correct answer ✔✔ the union of a single egg with a single sperm
What is the Ovum? - correct answer ✔✔ each month one ovum matures and is released from
the ovary (ovulation)
- the egg is considered fertile for about 24 hours
Sperm may reach the egg within - correct answer ✔✔ 5 minutes, though average time is 4-6
hours and sperm may survive within the woman's body for up to 3 days
Fertilization occurs in - correct answer ✔✔ outer third of fallopian tube
, In fertilization, what occurs once one sperm penetrates the egg? - correct answer ✔✔ the
membrane surrounding the egg becomes impermeable preventing the entrance of any
additional sperm = zona reaction
During fertilization, the nuclei of the ovum and the sperm merge and the chromosomes
combine resulting in - correct answer ✔✔ the full 46 chromosomes of human cells (23 pairs)
Both the egg and sperm contain - correct answer ✔✔ 23 chromosomes, 22 autosomes, and 1
sex chromosome
How long does it take the zygote to continue down fallopian tube after fetilization? - correct
answer ✔✔ 3-4 days
Implantation occurs in the uterus about - correct answer ✔✔ about 6-10 days after fertilization
What can women experience during implantation? - correct answer ✔✔ implantation bleeding
(spotting) as the enzymes produced by the blastocyst/zygote allow the fetus to burrow into the
endometrium
Implantation bleeding can be mistaken for a - correct answer ✔✔ menstrual period especially
since this occurs close to the time of the first missed period
_____ determines the sex of the fetus - correct answer ✔✔ male
When is the embryonic stage? - correct answer ✔✔ day 15 to 8 weeks
Week _____ make up the fetal stage of development - correct answer ✔✔ 8 through 40+
