In case of asexually reproducing organisms, mitosis is the method used for cell division and reproduction in cells. ... Example:Reproduction in Amoebaby binary fission or Plasmodium by multiple fission. Sexually reproducing organisms undergo meiosis wherein the chromosome number is halved to form gametes.
23 pairs of chromosomes are present in human being . out of these, one pair is of sex chromosomes. two type of sex chromosomes are found in human being X and Y. male contain one X chromosome and one Y chromosome (XY),while female contains two copies of X chromosome (XX).sperm has either X or y chromosome, while the egg has only X chromosome. so,if the sperm carrying y chromosome fuses with the egg, it results in the formation of a male child , and if the carrying X chromosome fuses with the egg, the results in the formation of a female child. thus , there is an equal chance of fusion of either X or Y chromosome with the egg. therefore, we can say that the sex of the newborn child is matter of chance and none of the parent is responsible for it. sex determination in human being is below.
