Easy ha ! keoke !
Its all related to genes
as grandparents genes got first alter when they undergo crossing in the father of the child then It again alter when they under go crossing with genes of the mother of the child so this occurs
Explanation:
The two parents involved in sexual reproduction produce gametes which fuse together forming a zygote. It gradually develops into a young child showing certain similarities with the parents.
Since, the child inherits its characters from both the parents the resemblance with them is very close.
The grandparents and the child are less closely resembling because a gap of gene pool is created by the parents of the child.
Variations of two generations mixing together and addition of new variations from parents, increases the difference between them to a greater extent. Hence, a child resembles more closely its parents than the grandparents.
