If you are talking about physical attractiveness, there is no relationship with birth order.

Can a child have higher IQ than parents?

IQ is influenced by a combination of genetic and environmental factors, so a child's IQ can be higher or lower than that of her parents. The specific combination of genetic traits inherited from both parents, as well as environmental influences, can contribute to variations in IQ.

Do first borns live longer?

This analysis found that the protective effect of being first-born is driven mostly by the young maternal age at person's birth (being born to a mother younger than 25 years). Being born to a young mother is the major predictor of human longevity (OR = 2.03, 95% CI = 1.33–3.11, p = 0.001; see also Fig. 1).

Can a low IQ mother have a high IQ child?

IQ is partly heritable (around 50%) and your parent's IQ could be a result of huge environmental factors like education and professional development as well as child-hood care. But low IQ parents can give birth to a high IQ child simply through a mix of genes they carry and the environment they create for you.

Does high IQ run in families?

Early twin studies of adult individuals have found a heritability of IQ between 57% and 73%, with some recent studies showing heritability for IQ as high as 80%. IQ goes from being weakly correlated with genetics for children, to being strongly correlated with genetics for late teens and adults.

What is the hardest sibling to be?

Why is first child more like father?

The idea that most firstborns look like their father is not universally supported by scientific evidence. While there may be some studies suggesting a correlation between a child's resemblance to their father and the father's involvement in caregiving, there is no definitive scientific consensus on this matter.

Why do beautiful people have daughters?

It appears that natural selection does help individual genes to spread, by subtly biasing the offspring sex ratio so that beautiful people, who can benefit from having a daughter, do indeed have slightly more daughters than ugly people, who cannot so benefit.

Does the first child get the best genes?

Somewhat surprisingly, in both our study and in previous ones, there is no evidence that younger children are born disadvantaged: if anything, later-borns are actually on average heavier and healthier at birth. Thus, the birth order effect does not seem to be related to an obvious biological advantage at birth.

Can younger sibling have higher IQ?

Although this is a robust and statistically significant finding the IQ difference is small. It means that in six out of ten cases the older sibling will have a higher IQ than the next youngest sibling. Conversely, it also means that in four out of ten cases younger siblings have a higher IQ.
