The Meosis II is responsible for formation of different gamates.
From
the above chart we can see haw from a single somatic germ
cell(2n)four gametes(n) is produced.
Now the fact is that there are many combination of chromosomes in the gametes and every time different type are fertilized so every time differnt offsprings are produced and every time different genes expressed themself. So the siblings are different by apperance.

2. A diploid cell contains two pairs of chromosomes, which we will call 1 and 2. Assume chromosome! is clearly larger than chromosome 2. Each chromosome pair contains a maternal and a paternal member (e.g. 1 and 1 & 2 and 2"). An allele called G is localized to 1" whereas an allele called g is on chromosome 1P. Allele R is localized to 2m whereas alleler is localized to 2. Using these designations and clearly drawn and labeled chromosomes,...
