Welcome to the NCERT Solutions for Class 12th Biology - Chapter Human Reproduction. This page offers a step-by-step solution to the specific question from Exercise 1, Question 19: in our society the women are often blamed for givi....
Question 19
In our society the women are often blamed for giving birth to daughters.
In our society the women are often blamed for giving birth to daughters.
Can you explain why this is not correct?
Answer
All human beings have 23 pairs of chromosomes. Human males have 22 pairs of autosomes and contain one or two types of sex chromosome. They are either X or Y. On the contrary, human females have 22 pairs of autosomes and contain only the X sex chromosome. The sex of an individual is determined by the type of the male gamete (X or Y), which fuses with the X chromosome of the female. If the fertilizing sperm is X, then the baby will be a girl and if it is Y, then the baby will be a boy. Hence, it is incorrect to blame a woman for the gender of the child.
