Table 3

Calculation of crossover genetic sequence for children.

Parent 1	4	6	5	2	3	1
Parent 2	6	4	2	5	3	1
(Parent 1 + parent 2) × 0.5	5	5	3.5	3.5	3	1
Children sequence	5	5	4^1	4	3	1
Children sequence after roundup	5	6^2	4	1	3	2

1 The mean value of the parents 1 and 2 is 3.5; thus, the children will be rounded up in value 4. 2 Because children’s sequence 5 overlaps with the first genetic sequence 5, they are assigned to 6.
