Question

What is the probability of having a male child from a random fertilization event?

विकल्प

• 1.0 or 100%

• 0.50 or 50%

• 0.25 or 25%

• 0.75 or 75%

Answer 1

The probability of having a male child is 0.50 or 50% because 50% of male sperms carry the Y chromosome. When these Y-bearing sperms randomly fertilize X-bearing eggs from the mother, there is a 50% chance of producing a male (XY) offspring.
