জনসংখ্যাৰ সংৰচনাত লিংগ আনুপাতিক সংৰচনাৰ প্ৰভাৱ কি বৰ্ণনা কৰা​

Answer 1

Answer:In the absence of manipulation, both the sex ratio at birth and the population sex ratio are remarkably constant in human populations. Small alterations do occur naturally; for example, a small excess of male births has been reported to occur during and after war. The tradition of son preference, however, has distorted these natural sex ratios in large parts of Asia and North Africa.
