Actually, It's Fraternal and not faternal. They even have spell-check on this site to make sure you don't make a mistake and you made a mistake correcting the former idiot!............Idiot!!!!!!!!!
Another name for maternal twins is identical twins. Maternal twins come from a single fertilized egg that splits into two, resulting in two babies with the same genetic makeup.
monozygotic or maternal twins
Female twins that are not identical are called fraternal twins. Fraternal twins occur when two separate eggs are fertilized by two separate sperm. Maternal twins refer to twins that share the same mother but can include both identical and fraternal twins.
No, it has to run on your side, as far as I have read anyway.
The likelihood of having twins varies depending on factors such as genetics, age, and ethnicity. On average, twins occur in about 1 in 30 births. Factors such as fertility treatments, family history of twins, and maternal age can increase the chances of having twins.
Identical twins are more likely to occur from a single fertilized egg splitting into two embryos, resulting in genetic duplicates. Fraternal twins result from two separate eggs being fertilized by two different sperm cells. Identical twins are not influenced by genetics or family history, whereas fraternal twins can be influenced by both maternal and paternal genetics.
Identical twins occur when a single fertilized egg splits into two embryos, resulting in genetically identical individuals. The occurrence rate of identical twins is approximately 3 to 4 per 1,000 births, making them relatively rare compared to fraternal twins. Factors such as genetics and maternal age can influence the likelihood of having identical twins, but the process itself is largely random.
Fertanal twins, or fraternal twins, are more commonly born to women of African descent, with studies indicating that they have the highest rates of twinning. This is followed by women of European descent, while women of Asian descent tend to have the lowest rates of fraternal twins. Factors such as genetics, maternal age, and the number of previous pregnancies also influence the likelihood of having fraternal twins.
Twins typically share a gestation period of about 37 weeks, which is slightly shorter than the average 40 weeks for a singleton pregnancy. While most twins are born prematurely, a gestation period of 34 to 36 weeks is common for many twin pregnancies. Factors such as maternal health and the type of twins (identical or fraternal) can also influence the length of gestation.
As of recent estimates, approximately 1 in every 42 births worldwide results in twins. This means that there are around 1.6 million twin births each year globally. The prevalence of twins can vary significantly by region, influenced by factors such as genetics, maternal age, and fertility treatments. Overall, the total number of twins currently living in the world is estimated to be around 10 million.
Twins can sometimes be predicted based on factors such as family history, maternal age, and certain fertility treatments. For instance, women over 30 are more likely to conceive fraternal twins, and those undergoing in vitro fertilization (IVF) often have higher chances of multiple births. However, predicting the exact occurrence of twins in any given pregnancy remains uncertain and cannot be guaranteed.
It doesn't work that way. A heifer calf is only infertile if she is twinned with a bull calf and if her and that bull calf share the same placental tissues. In most cases such twins are fraternal, but simply stating that fraternal twins versus maternal twins are more prone to infertility than the other is stating falsehoods.
