Question 1

if you have identical twins, will they both develop the same genetic/inherited disease at the same point?

Accepted Answer

Depends: If it's something that fully expresses itself with no modification (such as huntington's), yes. If it's going to express itself but is lifestyle-modifiable (type ii diabetes), timing will differ. The diseases for which there's a genetic component (diabetes, lupus, multiple sclerosis, many others) have only one twin affected more often than not -- you can find details.

Question 2

my husband has multiple sets of fraternal twins on his side and i have identical twins on my side, is the twin gene carried on the male side or woman?

Accepted Answer

Female Side: Genetic increase for twins is due to female tending to ovulate more than one egg at a time, so trait is for fraternal twins (not identical) and carried by mother.

Question 3

something wrong with today's genetic makeup because diabetes is on the rise worldwide, not exclusively to the obese but also to the slim. why?

Accepted Answer

Wrong diet: Diabetes is on the rise, mostly due to poor dietary habits, high intake of processed starch and sugar and low intake of lean protein and plant and fish based fat. Also lack of exercise. All of these contribute to Insulin resistance and in long term pre-diabetes and diabetes. There are many normal weight people with high abdominal fat which causes them to develop diabetes type 2.

Question 4

can you tell me how are individual human characteristics eg. colour blindness a product of our genetic makeup?

Accepted Answer

Genetics-Epigenetics: We have 46 chromosomes. These contain our genetic make-up-The 46 chromosomes are identical in all 50 Trillion cells.We got 23 from mom and 23 from dad-These 46 chromosomes have  30,000 genes-These genes make up the DNA that instructs each/every cell on what to do, what to specialize in, and when to do it (when to turn on and when to turn off and when to die)-Color blindness (or eye color)is fixed

Question 5

does cerebral palsy affect the genetic makeup of a child? my bestfriend is born from an american father and an asian mother. he married an asian woman as well and had a son. the son has cerebral palsy and looks nothing like his father. my bestfriend looks

Accepted Answer

Cerebral : Cerebral palsy does not affect genetic makeup.

Question 6

are fraternal or identical twins more common?

Accepted Answer

Yes: Fraternal twins are 3 times as frequent as identical. Fraternal twins happen when there is double ovulation and 2 eggs get fertilized. They are the type of twins that run in families. Identical twins come from 1 fertilized egg which separate in early gestation. Depending on when they separate, the babies can be in 2 distinct sac (di/di), 2 sacs within a shared sac (mono/di) or 1 sac (mono/mono).

Question 7

does identical twins have different sacs?

Accepted Answer

Some do some don't: If two twins share the same sac, they're identical. (almost always works.) the pathologist who examines the placenta can tell. Identical twins can have two sacs, or one sac; if there are two sacs, there can be one or two chorions.  Fraternal twins won't share chorions or sacs.

Question 8

why would my pediatrician be concerned about my 15 month (13 adjusted) identical twins girl's height?

Accepted Answer

We always watch it: Pediatricians always watch the height, weight, and head size for a baby or toddler. That's how we know if the growth is fine. Sometimes, two or three measurements are needed to get an accurate number on a squirming baby. We get concerned if a number is "off the graph" on the growth chart, or if numbers are trending too high or low for a particular child compared with her peers, sibs, or parents.

Question 9

can there be male and female identical twins?

Accepted Answer

No..identical!: As the word identical means: identical! thus must be of the same gender. There are fraternal twins and that can be either gender or one of each...:-)).

Question 10

how can identical twins be very different sizes?

Accepted Answer

Identical twins: Identical twins share a placenta. It certain circumstances the amount of placental blood flow to one twin may be more than to the other twin. That effects the growth of the twins.
