Q. Can two normal individuals of the same species with sexual reproduction have identical karyotypes and identical genomes? And how is the human karyotype usually represented?
Except for clones individuals created from nucleus transplantation, like the monozygotic twins and Dolly sheep, it is very unlikely the genomes of two individuals of the same species and produces by sexual reproduction to be identical. Nevertheless the karyotypes of two normal individuals of the similar species and of the same sex are always identical. The human normal karyotype is symbolized by the formula 44+XX for women and 44+XY for men.
