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.
Is common better than rare?
Rare by far
How many syllables in rare?
Rare only has one syllable.
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 occur when two separate eggs are fertilized by two different sperm cells. Identical twins occur when a single fertilized egg splits into two embryos, which then develop into two genetically identical individuals.
Can conjoined twins be different gender?
Yes, conjoined twins can be different genders if they develop from fertilized eggs that did not fully separate during early development. This rare occurrence is known as dizygotic (fraternal) conjoined twins.
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.
Are conjoined twins always identical?
No, conjoined twins can be either identical or fraternal. Identical twins result from a single fertilized egg splitting into two embryos, while fraternal twins occur when a woman releases two separate eggs that are each fertilized by different sperm.
How do you determine who is the father if identical twins have same dna?
If identical twins have the same DNA, it would be impossible to determine which twin is the biological father based on genetic testing alone. In such a case, additional evidence or alternative testing methods would be needed to establish paternity.
Dads a non identical twin can his son have twins?
it's possible but twins are rare
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.
