Answer:

A child's gender (male or female) is determined by the chromosome that the male parent contributes.

Explanation:

Females have XX sex chromosomes. Males have XY sex chromosomes. A male infant results if the male contributes his Y chromosome while a female infant results if he contributes his X chromosome.  Therefore, it is actually the King's fault that he is only producing female heirs.

The gender of a child is determined by the s ex chromosomes present in male and not by the female.

What are s ex chromosomes?

  • Humans have 23 pairs of chromosomes.
  • 22 of these pairs are called autosomes and are same in both male and female.
  • The 23rd pair chromosome is different in male and female and are called s ex chromosomes because determines the s ex of a child.
  • The female has two copies of X chromosomes whereas males has one X and one Y chromosome.
  • During fertilization, the embryo receives one set of chromosomes from each parents.
  • Child with XX chromosomes will be girl and child with XY chromosome will be boy.

As, the mother can only give X chromosome then the gender of child is determined by the chromosomes he received from his father as it has both X an Y chromosomes.

Hence, the female should not be blamed if she gives birth to only daughters.
