WHENE the division of the zygote is not complete,is pairs of siamese twins who maybe joined at the buttocks,chest,neck.
Although there is a genetic component to twin births, many multiple births are not genetic. If one generation has twins, the next generation may also have twins. The likelihood of twins reduces with succeeding generations that do not have twins. Multiple births does not have patters such as generation skipping, and is never guaranteed.
Siblings can be the same age, in the form of twins and triplets, and other various forms of the multiple births.
It takes 40 wks for a foetus to reach full term maturity in single or multiple births. Multiple births are induced earlier if there are problems.
No, not in particular. The mutable signs (Gemini, Virgo, Sagittarius, Pisces) in general indicate multiple births.
The number of multiple births per year can vary depending on the population and region. In the United States, for example, about 3% of all births are multiples, which includes twins, triplets, and higher order multiples. This percentage has been relatively stable over the years.
They take fertility drugs to get pregnant exactly WHEN they want while increasing their changes of multiple births.
Yes, because after 35 your probability for having multiple births goes up.

The most common type of multiple births is twins, specifically dizygotic (fraternal) twins, which occur when two separate eggs are fertilized by two separate sperm cells. This type of twin birth is more common than monozygotic (identical) twins, where a single fertilized egg splits into two embryos. Factors such as maternal age, genetics, and the use of fertility treatments can influence the likelihood of having twins.
Yes, there is 4 sets of identical twins in every 1000 births.
Multiple births can sometimes be predicted based on certain factors such as genetics, maternal age, and the use of fertility treatments, which increase the likelihood of twins or higher-order multiples. However, it is not possible to accurately predict multiple births in every case. Ultrasound and other medical assessments can confirm multiple pregnancies once they occur, but prior indicators are not definitive. Overall, while some factors can suggest a higher likelihood, the exact occurrence of multiple births remains uncertain until confirmed by medical imaging.
Multiple births, such as twins, triplets, or higher-order multiples, account for approximately 1-3% of the total world population. The rate of multiple births varies by region and is influenced by factors like maternal age, fertility treatments, and genetic predispositions. Overall, while multiple births are relatively rare, their occurrence has been increasing in recent years due to advancements in reproductive technologies.
