From my teacher he said all living beings have to have two chromosmes to live. One from father and other from mother
In humans, the sex determination is of xy type. That means male babies have one x and one y chromosome and females have both xx chromosomes. Therefore, all the babies born, either male or female have at least one x chromosome.
Yes, an embryo can develop with one X chromosome, rather than the XX or XY chromosome pair. An example of this is girls born with Turner's syndrome, who have only one X chromosome.

When a person is born they get one chromosome from the mom and one from the dad. A female has XX chromosomes a male has XY Cromosomes. So a male would get the Y from the dad and the X from the mom.
Because males have only one X chromosome, any recessive allele present on that X chromosome will be expressed in the phenotype. In females, who have two X chromosomes, the presence of a dominant allele on one X chromosome can mask the expression of a recessive allele on the other X chromosome.

In males, sperm contain only one sex chromosome. In females, eggs contain only one sex chromosome.
Most girls are born with two X chromosomes, but girls with Turner syndrome are born with only one X chromosome or they are missing part of one X chromosome. The effects of the condition vary widely among girls with Turner syndrome. It all depends on how many of the body's cells are affected by the changes to the X chromosome.
In males, sperm contain only one sex chromosome. In females, eggs contain only one sex chromosome.

Turner Syndrome
The DNA of the Y-chromosome is the DNA that is transmitted only from father to son. This is because women have two X-chromosomes, one of which is given to each child. But men have one X-chromosome and one Y-chromosome. So if a father gives a Y-chromosome to his child that child will be male, while only females receive the father's X-chromosome.
