The circle in the figure can be completed as:
A is a girl. The ovum carrying X-chromosome has been fertilised by a sperm carrying X-chromosome, resulting a zygote with XX combination of sex chromosomes. So, the child born will be a female.
B is a boy. In this case, the X-chromosome carrying ovum has been fertilised by a sperm carrying Y-chromosome. This results in formation of zygote with XY combination of sex chromosomes. So, the child born will be a male.
