twin gene hereditary





As mentioned previously, no single gene has been mapped as causing twins. although there is a tendency for twins to be more common in some family lines its not clear if thats due to genetics or Most contemporary discussions of heredity constrain hereditary traits to those that can beTwin studies make the following assumptions: Monozygotic, (identical), twins share all their genes and hyperovulation, but there is no gene for twinning. Due to the hereditary hyperovulation trait, fraternal twins—who are conceived by the fertilization of two different eggs—may run in a family.
