When a haemophilic carrier female marries a haemiphilic man then due to ther genotypes
Xc=carrier of haemophilia
Xn=normal
Y=dont carry haemophilic genes
so here we go!

2=XcXn
3=XcY
4=XnY
so from whole 4 there is 50% parobability

This information is encoded within the cell nucleus in 6 billion subunits of DNA called base pairs. These base pairs are packaged in 23 pairs of chromosomes, with 1 chromosome in each pair coming from each parent. Each of the 46 human chromosomes contains the DNA for thousands of individual genes.</span>
