For these people, the sex of the baby is immaterial. People are slowly becoming aware that women are not a drain on the family's resources just by the fact of their birth. Prejudice, ignorance and circumstances can make them that way. Daughters do not have to be viewed as a burden. People who do not educate their daughters, who do not give them equal opportunities and who do not fight against the evils of dowry force their daughters into a position where they become a burden on the family s resources.
Every egg produced by the woman carries a single X chromosome.
If a female sperm fertilizes the egg, the result is a baby girl. If a male sperm fuses with the woman's egg, a baby boy will be born. For conception to occur, a single sperm has to swim through the cervical mucus and mate with the ovum in the Fallopian tubes. The most important thing, of course, is to ensure that conception occurs. The timing is critical.
