Explain with the help of a flow chart that in human beings father is responsible for the sex (male or female) of the child.
Solution
Flowchart
Gametes - Mother's Ova: X, X ; Father's Sperm: X, Y
Zygote/Offsprings - XX (Female child), XX (Female child), XY (Male Child), XY (Male Child)
If a sperm carrying X chromosomes fertilizes an ovum which carries X chromosome, then the child born will be a girl.
If a sperm carrying Y chromosome fertilizes an ovum which carries X-Chromosome, then the child born will be a boy.
