What else can I help you with?
How rare is a femoral hernia for a 41 year old female weighing 8 stone and what are the true risks of strangulation while waiting for surgery?
Don't know how rare, but as a 38 yr old woman, I unknowingly had mine for eight years and carried twins to full term before anything happened.
How rare is a hole in one in golf?
That depends on which hole. Shorter holes will have more common hole in ones than long ones. In general, still very rare.
What quarters are rare?
1924 SState quarters are not worth more than face value unless they have the "S" mintmark. Pre-1965 quarters are rare, because they have a high silver content.
What is the longest time interval between the birth of twins?
The longest documented time interval between the birth of twins is 87 days. This unusual case occurred in 2012 when a woman in Ireland gave birth to one twin prematurely, and the second twin was delivered nearly three months later. Such extended intervals are extremely rare and typically involve medical intervention to prolong the pregnancy of the second twin.
What are people with two heads called?
People with two heads are often referred to as "conjoined twins" or "dicephalic twins" when each twin has a separate head but shares a single body. This rare condition occurs due to incomplete splitting of a fertilized egg during early development. The medical term for this specific type of conjoined twin is "dicephalic parapagus." Such individuals may have varying degrees of shared organs and limbs, depending on their specific anatomy.
Are quadruplets always identical or always fraternal or can they be either?
Quads can be identical, fraternal, or a pair of identical twins. Identical quads are rare- that would require 1 egg divide into 2, and then divide again into two. Most quads are fraternal.
How Do Fraternal Twins Occur and Identical Twins Occur?
Fraternal twins (dizygotic twins) are simply two fertilized eggs that are implanted in the uterus at the same time. Identical twins (monozygotic twins) is one fertilized egg that separates into two embryos. In most cases, identical twins share one placenta, but have separate amniotic sacs. In some cases, they have two placentas. In rare cases, they share both the placenta and the amniotic sac.
Can conjoined twins be different gender?
Nature has various safety valves. That is one of them. Conjoined Twins are identical twins with a natural connective bond, therefore they always take the same sex. Fraternal twins, like the fictional Bobbseys, can be Boy and Girl.
How is a fraternal twin different than other twins?
Fraternal means "brother-like." Identical twins result from a single fertilzed egg dividing into two separate embryos so the twins share all DNA. Fraternal twins result from two different eggs being fertilized by two different sperm at the same time. The babies are then born at the same time, but only share 25%of their DNA with each other, which is the same amount that siblings born at different times share. The word fraternal used in social organizations, like "the fraternal order of"...refers to the thought that the members are like brothers to each other. Modern french uses the word frere to mean brother.
Can identical twins be of different sexes?
They can be. While identical twins always have to be the same gender, fraternal twins usually are not. However this is not always the case. Identical twins occur because they inhabit the same egg. Fraternal twins because two eggs were fertilized at the same time. So fraternal twins could be the same gender, but usually they are of the opposite gender.
Clomid and twins?
Yes! I took Clomid for less than six cycles and the two times I actually ovulated I released more than one egg. In fact I am currently eight weeks pregnant with fraternal twins right now due to the clomid! So if you don't want twins, think twice! this is what i found on the web!Twin pregnancies may occur in as many as 5% of the women who use Clomid. Triplet pregnancies are far more rare.
Dads a non identical twin can his son have twins?
it's possible but twins are rare
Are conjoined twins always identical?
Yes. Conjoined twins form when the fertilized egg starts to split, but does not completely split into two. Improved. There are no known cases of opposite sex Conjoined twins but that does not mean it can not happen. it is generally believed that identical twins means actually identical but the correct term now is actually monzygotic twins meaning one sack the reason they use this term is because to simply put it identical twins is actually rare when twins are born of the same sack Mono they are rarely actually identical and as such it is possible for a monozygotic twins to not completely sperate but in rare cases actual identical twins can in fact be of seperate sexual phenotype's they usually have some other defect
How do you determine who is the father if identical twins have same dna?
Identical twins will have the same father, so a paternity test is done just like for any kid. With fraternal twins, it is possible, but very, very rare, to have different fathers for the babies.
Are twins that can only be two girls or two boys identical?
No. In order for them to be identical they needed to start off as the same cell and divide so at first their DNA is identical meaning they have the same sex. During development slight changes may occur but the sex always stays the same. Boy-girl twins are always two different cells meaning that they are not identical. The term for boy-girl twins is furturnal. You can however have boy-boy twins and girl-girl twins that are not identical and they are also called furternal. So basically, identical twins start off as one cell that divides and furternal are two individual cells. There is polar body twinning, that's when the egg splits before fertilization, and that can cause a male and a female. This is called semi identical twins or half twins. They share 75% of their genetic markers.
How do you know what kind of twins they are?
Genetic testing is the only way to positively identify what type of twins you are having. Identical or monozygotic (MZ) twins occur when a single egg is fertilized to form one zygote (hence, "monozygotic") which then divides into two separate embryos. Half-identical or semi-identical twins (also referred to as "half twins") are the result of a very rare form of twinning in which the twins inherit exactly the same genes from their mother but different genes from their father. Fraternal or dizygotic (DZ) twins (also referred to as "non-identical twins" and in cases of females, occasionally sororal twins) usually occur when two fertilized eggs are implanted in the uterus wall at the same time. When two eggs are independently fertilized by two different sperm cells, fraternal twins result.
Can dogs give birth to twins?
Yes they can but it's extremely rare. Most dogs usually give birth to single puppies in one litter but sometimes though, they can have two puppies born in the same sac which you would call twins but the identical kind not fraturnal. Just like humans, dogs can have sets of identical twins or fraternal twins. But the chances are, when your dogs is pregnant she may only have single puppies and no twins. But in one out of a million dog pregancies people have reported that their dogs gave birth to twins. It's rare but it's quite possible.
