Is sex at birth a biological coin toss? Insights from a longitudinal and GWAS analysis
Overview
Paper Summary
This study found that offspring sex at birth doesn't follow a simple coin toss probability within families, with children's sex clustering more than expected. Maternal age at first birth and genetics are linked to having single-sex offspring, suggesting both biological and behavioral factors are involved.
Explain Like I'm Five
Scientists found that having a boy or a girl isn't always like flipping a coin. Some families tend to have more boys or more girls, and this can be linked to the mom's age or family genes.

Rating Explanation
This is a well-conducted study with a large sample size, robust statistical methods, and intriguing findings about sex clustering. The beta-binomial distribution modeling and GWAS analysis provide valuable insights into the complex interplay of genetics, biology, and behavior in determining offspring sex within families. The identified limitations are acknowledged and do not negate the significant contributions of this research.
