Solution

No. The female produces eggs that carry an X chromosome, while the male produces X-bearing and Y-bearing sperm. An X-bearing sperm results in an XX offspring, while a Y-bearing sperm results in an XY offspring. Therefore, the sperm determines the child’s chromosomal sex, and the mother should not be blamed.
