The interpretation may be that since twins have a partner from birth, they do not have the same need for marriage as singletons but have more experience in maintaining a relationship if they do marry.
It's equally unsurprising that a Danish study found that twins are less likely to get married than non-twins. As twins have a partner from birth, the study suggests that they may not have the same desire for marriage as singletons.
Twins are enmeshed with each other
Psychologists say it's not just genetics, but also factors like comparison during growth years, lack of individual identity, etc. The relationship often becomes codependent. You may begin to feel like an outsider in an intimate relationship, even though you're the one dating a twin.
Indeed, analysis on the offspring of twins shows that they are not exceptionally fertile when compared to the rest of the population.
Twin sisters who married twins reveal their sons are genetic brothers and cousins. Identical twin sisters who married identical twin brothers have given birth to sons who are brothers and cousins at the same time.
Since identical twins share the same DNA, the children of two pairs of identical twins are legally cousins, but genetically more similar to siblings.
Identical twins have the same genetic material, but as you can see, every egg they both make is different. Every sperm a man makes is different. Hence the chances of their babies being identical are pretty close to zero. The kids wouldn't be any more alike than any brother or sister.
Twins are more or less equally likely to be female or male. Contrary to popular belief, the incidence of twins doesn't skip generations.
They come from the same fertilized egg and share the same genetic blueprint. To a standard DNA test, they are indistinguishable. But any forensics expert will tell you that there is at least one surefire way to tell them apart: identical twins do not have matching fingerprints.
The longest interval between the birth of twins is 90 days, in the case of Molly and Benjamin West, dizygotic (fraternal) twins born in Baltimore, Maryland, USA to parents Lesa and David West (all USA) on 1 January and 30 March 1996.
Analyses of data from the National Longitudinal Study of Adolescent to Adult Health show that MZ twins were significantly more physically attractive and healthier than dizygotic (DZ) twins and singletons.
Multiples are about twice as likely as singleton babies to have birth defects, including neural tube defects (such as spina bifida), cerebral palsy, congenital heart defects and birth defects that affect the digestive system. Growth problems. Multiples are usually smaller than singleton babies.
The survey found: That 4.3% of respondents divorced during the pregnancy or following the birth of multiples (indicating that the divorce rate among this group may not be as high as many have speculated.) Over 95% of the marriages were intact.
In actuality, twins can suffer and be stifled by one another. While the twin attachment is strong, enduring, and very close, the twin bond can also be fraught with competition, obligation, anger, and resentment. Twins learn to take care of one another from birth. Hands down, they are deeply attached.
Compared to mothers without twins at first birth, mothers with twins had higher rates of divorce (OR 1.08, 95% CI 1.01–1.16; predicted absolute risk 13.7% vs 12.7%, p = 0.02). Women who had children later, married later, had at least some college education, and were white were also less likely to divorce.
Semi-identical twins are rare, and doctors say they've identified the second case ever | CNN. You've probably heard of identical and fraternal twins, but a report released this week says there's a third kind -- sesquizygous twins or "semi-identical." Researchers say they share anywhere from 50 to 100% of their genomes.
Identical (i.e., monozygotic, or MZ) twins share 100 percent of their genes, whereas fraternal (i.e., dizygotic, or DZ) twins generally share only 50 percent of their genes.
Monozygotic (identical) twins will have the same blood type, with a few very rare exceptions. Dizygotic (fraternal) twins may have the same blood type, or they may have different types. Therefore, it may be concluded that twins with differing blood types are dizygotic, or fraternal.
If twins are a boy and a girl, clearly they are fraternal twins, as they do not have the same DNA. A boy has XY chromosomes and a girl has XX chromosomes. Girl-boy twins occur when one X egg is fertilized with an X sperm, and a Y sperm fertilizes the other X egg.
Although this is quite rare it can happen and it's called superfetation. Two babies are conceived from separate acts in two different cycles. These babies can be from the same father or two different men. When heteropaternal superfecundation occurs, the babies are from different fathers.
The biological phenomenon of giving birth to twins with two different biological fathers is called heteropaternal superfecundation. In a rare and surprising event, a 19-year-old Brazilian woman gave birth to twins who belong to two different biological fathers.
For the most part, twins and multiples share the same birthday. However, depending on the time of day the babies are born and how long the timespan is between each baby's birth, twins can be born on different days.
