Summary: A recent research reveals that prominent roles in twin relationships are highly influenced by developmental differences, with normally developing twins seen as dominant over their nontypically developing siblings. Even if development difficulties improve, this hegemony imbalance persists throughout childhood.
Dynamics is affected by genetic resemblance, since monozygotic twins have more symmetrical connections than dizygotic twins. Parental views frequently reinforce dominance jobs through prejudices that embellish differences, highlighting the need for strategies to cultivate healthy relationships.
Major Information
- Developmental Impact: When paired with nontypically developing siblings, typically developing triplets are regularly seen as dominating.
- Biological Control: Dizygotic twins exhibit more balanced dynamics than monozygotic twins.
- Parental Role: Parental biases, such as the” compare effect”, promote dominance trends in sisters.

A research conducted by Prof. Ariel Knafo-Noam and Dr. Yonat Rum from the Hebrew University of Jerusalem, along with Dr. Hila Segal and Adi Barkan from The Academic College of Tel Aviv–Jaffa, explores how development differences affect the dynamics of hegemony in mini connections from birth to adulthood.
Sisters, unlike daughters, share the same time and often a similar environment, creating special interpersonal relationships where standard elements like birth get play no role.
This study, which was published in Family Relations, examined how differences in twins ‘ development conditions, especially when one baby has a developmental condition but the other does not, alter their supremacy dynamics over time.
More than 1,500 families of monozygotic and dizygotic sisters between the ages of 3 and 9 were questioned during the study. According to the study, parents constantly perceived the typically developing twin as the strong sibling when one twin was generally developing and the other twin was generally developing as the strong sibling.
This dominance imbalance remained constant throughout the entire child’s development, even after the nontypically developing twin’s development difficulties were overcome. No major differences in supremacy were found in mini sets where both siblings shared the same evolutionary condition, whether standard or uncommon.
These findings support the hypothesis that supremacy imbalances are caused by the asymmetry in abilities between the twins rather than by the development condition itself.
Familial opinions were important in shaping these relationships. The study cited earlier research that demonstrated that kids frequently emphasize differences between twins through a preconceived notion known as the” compare consequence,” a bias that exaggerates perceived variations.
This familial tendency you reinforce dominance roles, which affects how twins interact with one another and influences how long-term relationships develop between the twins.
The findings are in line with community systems theory, which posits that families are interconnected units with different roles and behaviors.
In this environment, familial perceptions and behaviors may unwittingly consolidate certain tasks, such as “dominant” or” submissive”, in sisters ‘ relationships.
Incidentally, genetic similarity also influenced supremacy designs. Compared to dizygotic twins, who share nearly identical biological materials, were more likely to exhibit symmetrical dominance relationships, yet when developmental problems differed.
This suggests that identical twin pair may have more healthy relationships and genetic factors that influence dominance activities.
The study also found that first dominance roles are likely to continue even when a nontypically developing twin’s development condition improves.
This persistence can be understood through position theory, which explains how home roles, once established, become entrenched through both behavior and filial reinforcement. Parents are encouraged to create opportunities for more balanced dynamics in order to reduce the effects of ingrained dominance roles.
The long-term effects of these dynamics can be reduced by encouraging twins to engage in relationships outside their twinship, encouraging individuality, and providing opportunities for the less dominant twin to assert themselves in specific domains.
This study highlights the importance of parental awareness in navigating these dynamics and provides a nuanced understanding of how developmental differences influence twin relationships.
Parents and caregivers can foster healthier, more balanced sibling relationships that benefit both twins ‘ social and emotional development by addressing these patterns early.

“” You and me”: Parental perceptions on asymmetry in twins ‘ development and their dominance relationship dynamics” by Ariel Knafo-Noam et al. Family Relations
Abstract
” You and me”: Parental perspectives on the dominance relationship dynamics of twin development and asymmetry in their dominance relationships
Objective
This study looked at whether nontypical development had a significant impact on twins ‘ overall development throughout their early years of marriage. Background Dominance dynamics, affecting siblings ‘ well‐being, are different in twins than in singletons for whom age and development often dictate sibling hierarchy.
These dynamics in twins, who share similar ages and developmental contexts, remain underexplored and demand further understanding.
Method
A longitudinal study surveyed 1, 547 mothers and 536 fathers of 322 monozygotic ( sharing nearly 100 % genes ) and 1, 199 dizygotic ( sharing 50 % genetic variance ) twin pairs, aged 3 to 8–9. Both parents reported on the twins ‘ relationships. Whether either twin had a developmental condition was reported by mothers.
Results
Whether either twins had typical or unusual developmental development was not found in similar developmental conditions dyads. Nontypically developing twins were less dominant than their typically developing cotwins in dyads where twins differed in the developmental condition. Even after the initial developmental problems were resolved, this dominance imbalance persisted throughout childhood.
Conclusion
Nontypical development does not, in itself, prevent children from exhibiting dominance behaviors in twinship, but it is more likely that the asymmetry in developmental conditions is related to the twins ‘ relationship.
Constraints and recommendations Parents ‘ perceptions suggest that twins with nontypical development may experience unbalanced relationships later in life because their co-twin is a typically developing child. However, demonstrating dominance might be possible for them in other contexts.
Caregivers must be able to learn these dominance dynamics in order to develop customized parenting plans and interventions to support the well-being of children.
