The principal of Mendelian inheritance in which each pair of chromosomes separates independently of every other pair when egg and sperm are formed is the principle of independent assortment

Explanation:

During the development of  reproductive cells, how the independent genes separates from each other is described by The Principle of Independent Assortment. It was Gregor Mendel to observe the characteristics of Independent assortment of genes in 1865. He observed this while studying pea plants genetics.  

Recombination is one of the features of independent assortment of genes. Meiosis is the phase during which it occurs. New gene combinations are produced by recombining DNA pieces. It includes the  maternal and paternal genes pieces and ensures that the assortment of genes takes place independently.

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
