Does the first child get the best genes?

First-borns aren't just healthier or smarter, but also they score higher on “emotional stability, persistence, social outgoingness, willingness to assume responsibility and ability to take initiative.” The researchers ruled out genetic factors; in fact, they uncovered evidence that later-born children might be ...

The researchers found that first borns have an advantage when it comes to emotional stability, persistence, being outgoing and social, an ability to take initiative and a willingness to take on responsibility, leading them towards top managerial positions.First-borns are 3 per cent more likely to have high blood pressure than second-borns and 7 per cent more likely than fifthborns. They're also 4 per cent more likely to be overweight than second-borns and 10 per cent more likely than fifth-borns. However, first-borns are more likely to report better mental health.For example, there are no genes for being a firstborn or a laterborn. Instead, birth order is best seen as a proxy for various environmental influences, particularly disparities in age, physical size, power, and status within the family.Firstborns tend to possess psychological characteristics related to leadership, including responsibility, creativity, obedience and dominance. They are also more likely to have higher academic abilities and levels of intelligence than their younger siblings.First borns score higher than their siblings in IQ tests as early as age one, the study has found. Although all children received the same levels of emotional support, first-born children received more support with tasks that developed thinking skills.A subsequent body of research, building over the years in the journal Evolution & Human Behavior, has delivered results in conflict with the 1995 paper, indicating that young children resemble both parents equally. Some studies have even found that newborns tend to resemble their mothers more than their fathers.First-born kids tend to be leaders, like CEOS and founders, and are more likely to achieve traditional success. Middle-born children often embody a mix of the traits of older and younger siblings, and they're very relationship-focused.The sex of the future baby depends on the father. From their mother, a baby always receives the X-chromosome and from father either an X-chromosome (which means it will be a girl) or a Y-chromosome (which means it will be a boy).Genetically, you actually carry more of your mother's genes than your father's. That's because of little organelles that live within your cells, the mitochondria, which you only receive from your mother.There's no set genetic rule that all first born daughters look like their dads, but in many cases – thanks to TikTok – we've seen this theory proved. However, we think this is nothing more than a cute opportunity for Das to be involved with their daughters' TikTok careers.In concluding the study, co-author and psychologist at the University of Padova in Italy Paola Bressan noted that to the best of her knowledge, “no study has either replicated or supported” the findings from the 1995 study that stated babies resemble their fathers.Experts say the best time to get pregnant is between your late 20s and early 30s. This age range is associated with the best outcomes for both you and your baby. One study pinpointed the ideal age to give birth to a first child as 30.5.“Firstborn children can be goal-oriented, outspoken, stubborn, independent, and perfectionistic,” Smelser says, and when you look at the way firstborns are nurtured, it starts to make sense why. “These traits are often reinforced by parents through their interactions with the child,” she says.According to Sulloway, 1995, Sulloway, 1996, firstborns are highly motivated to defend their favored status and to preserve valued parental resources. As a result, they are expected to be higher in extraversion than laterborns, specifically in the sense of being more assertive and dominant.In verse Exodus 13:2, God says, “Consecrate every firstborn male to me, the firstborn from every womb among the Israelites, both man and domestic animal; it is mine.” This is the first place where God is giving that instruction to the Israelites as a whole.The genetics of heightAs a general rule of thumb, your height can be predicted based on how tall your parents are. If they are tall or short, then your own height is said to end up somewhere based on the average heights between your two parents.Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors.Youngest children are also often described as spoiled, willing to take unnecessary risks, and less intelligent than their oldest siblings. Psychologists have theorized that parents coddle youngest children.A new study shows that first-born children tend to be smarter than their siblings and second-born children are more likely to cause trouble. The University of Edinburgh study reported that the oldest child tends to have a higher IQ and thinking skills than their younger siblings.If you're the youngest or middle child in your family, get ready for some unwelcome news: Your eldest sibling is likely right when they brag about being the oldest and the wisest.It seems that most first-born children look like their dads at birth – and throughout that first year of life.Sons can only inherit a Y chromosome from dad, which means all traits that are only found on the Y chromosome come from dad, not mom. Background: All men inherit a Y chromosome from their father, and all fathers pass down a Y chromosome to their sons. Because of this, Y-linked traits follow a clear paternal lineage.Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
