Genetic diversity


Genetic diversity

Suppose a child inherits chromosomes from parents and constructs a new pair of chromosome pairs.
A child can receive an 'A' or 'a' from his mother and a 'B' or 'b' from his father. So, the child can inherit chromosomes in the following four cases.

  1. A & B
  2. A & b
  3. a & B
  4. a & b

Since all the chromosomes of a person are 23 pairs, the number of cases that can appear is as follows.

223 = 8,388,608

Theoretically, to have genetically identical children, you should have more than 8 million children.
But, 'identical twins' are genetically identical.
