Genetics And Fetal Development

Front 1

Human Genome Project

Back 1

This project has elucidated some of the dispositions that DNA is responsible for predisposing a person to a particular disease.

Hint 1

Sounds like something you've heard before concerning homo sapiens...

Front 2

Preimplantation Genetic Diagnosis

Back 2

PGD is a diagnosis available to women prior fertilization to influence and predict genes and genetics.

Hint 2

Improves success rates and decreases multiple pregnancies.

Front 3

Karyotype

Back 3

What does a complete human genetic set look like?

Hint 3

Single word

Front 4

Fun fact

Back 4

Mitosis is the act of dividing cells to maintain them. Meiosis is the act of those cells duplicating to create sex cells.

Front 5

Human Chorionic Gonadotropin

Back 5

hCG this hormone is the hormone that influences progesterone to keep secreting to signal the corpus ludeum , thickening the uterine lining for pregnancy.

Hint 5

This is what determines pregnancy on a pregnancy test.

Front 6

Ectoderm

Back 6

The outermost cells.

Front 7

Mesoderm

Back 7

The middle layer; the lungs, heart, bones, and muscle

Front 8

Endoderm

Back 8

This is the inner most layer; the digestive tract, lining of the lungs, and the bladder.

Hint 8

At 14 days these layers are complete and the fetus becomes an embryo.

Front 9

The inner amnion

Back 9

There are two layers of fetal tissue. Which secretes amniotic fluid?

Front 10

The outer chorion

Back 10

This second layer of the fetal tissue forms the fetal portion of the placenta.

Hint 10

-Not amnion, but

Front 11

The Decidua

Back 11

This is the maternal tissue portion of the placenta.

Front 12

Errors of Cell Division

Back 12

Aneuploidy- abnormal chromosomal numbers.

Translocation- chromosomal fragments attaching to other chromosomes.

Hint 12

These are two abnormalities in meiosis, what are they called in laments terms?

Front 13

Autosomal chromosome abnormality

Back 13

Down syndrome- trisomy 21 extra chromosome from the egg is considered what chromosome abnormality?

Front 14

Sex chromosome abnormalities

Back 14

Turner's XO (monosomy)

Klinefelter's XXY (trisomy)

Trisomy X- XXX (trisomy)

Double Y- XYY (trisomy) are all what type of chromosomal abnormalities?
