This expert review explores the odds, providing informative insights for readers in the US. Introduction: Having twins has long fascinated and intrigued people around the world. While the occurrence of twins is relatively rare, it becomes even more intriguing when it seems to run in the family. In this expert review, we will explore the odds of having twins if it runs in the family, specifically focusing on the region of the United States. By delving into the genetic and environmental factors that contribute to the likelihood of twinning, we aim to provide informative and easy-to-understand insights for those interested in this captivating phenomenon. Understanding Twinning: To comprehend the odds of having twins if it runs in the family, it is crucial to understand the two primary types of twins: identical (monozygotic) and fraternal (dizygotic) twins. Identical twins occur when a single fertilized egg splits into two embryos, resulting in two genetically identical individuals. Fraternal twins, on the other hand, occur when two separate eggs are fertilized by two different sperm, resulting in two non
Does having twins depend on the male?
If the twins are present on your husband's/partner's side, it won't influence your chances of having twins. Remember, the gene for hyperovulation is only a factor for the mother. If your mother (or your grandmother or aunt) was or had fraternal twins, you might have the gene.
Which gender is more likely to be twins?
Sex determination in twins occurs as normal, with males having XY and females having XX. The sex of a fetus, even twins, can be identified via an ultrasound at week 14-21 of the pregnancy. Twins can consist of males, females, or both, with female twins being the most common.
What makes you more likely to have twins genetically?
Some women have versions (called alleles) of these genes that make them more likely to hyperovulate. This means there is a higher chance that two eggs could get fertilized at once, leading to fraternal twins. The gene versions that increase the chance of hyperovulation can be passed down from parent to child.
What determines the odds of having twins?
There may be an underlying genetic factor that predisposes someone to release more than one egg at a time, which increases the chance of having twins. Weight – There has been some consideration that people who are overweight are more likely to release more than one egg at a time, which may increase the chance of twins.
Is a male twin more likely to have twins?
Even though researchers haven't pinpointed the cause, some people are at an increased likelihood of having twins. According to The American Society for Reproductive Medicine, women who are fraternal twins have a 1 in 60 chance of having twins, and men who are fraternal twins have a 1 in 125 chance of fathering twins.
