Question
In the human beings the
statistical probability of getting
either a male or a female child
is 50:50 give reason and explain
with the help of a diagram​

Answer 1

Answer:

Explanation:

Therefore, possibility of fertilization of egg (22 + X) with sperm carrying 22+X chromosomes and hence chances of having a female child (44A + XX) is 50%. Likewise, there is 50% possibility that egg (22 + X) is fertilized with sperm carrying 22+Y chromosomes to have male child (44A + XY).

Answer 2

Explanation:

The sex of an infant is determined by the type of sex chromosome contributed by the male gamete. A male produces two types of sperms, one type bears 22+X composition and the other, 22+Y. Therefore, a male has 50% sperms with X chromosomes and the other 50% with Y chromosomes.

The sex of an infant is determined by the type of sex chromosome contributed by the male gamete. A male produces two types of sperms, one type bears 22+X composition and the other, 22+Y. Therefore, a male has 50% sperms with X chromosomes and the other 50% with Y chromosomes.Anyone of the two types of the sperms can fertilize the egg. If a Y bearing sperm fertilizes the egg, the zygote will be a male (XY) and when X bearing sperm fertilizes the egg, the resulting zygote will be female (XX). Since the ratio of the X chromosome and the Y chromosome in a male gamete is 50:50. The statistical probability of male or female infants is also 50:50.
