Final answer:
The statement about the ratio of male to female children being scarcely affected by culture is false, as cultural factors can significantly influence the sex ratio due to various reasons such as infant mortality and adult mortality rates.
Step-by-step explanation:
The statement that the ratio of male to female children is scarcely affected by culture is false. In reality, various cultural factors, such as gender roles, economic decisions, and government policies, can significantly influence the sex ratio. While the biological expectation is close to a 1:1 ratio, cultural factors can lead to different outcomes. For instance, the sex ratio at birth in the United States is approximately 105 boys to 100 girls, but due to higher male infant mortality rates, the prevalence of violence among young men, and higher male mortality from heart and lung disease, there are slightly fewer men than women in the country. Cultural practices and public policies vary widely around the world, and in some regions, these sex ratios can be even more skewed.
