What does allele output show?

It shows the odds of pure recessive traits vs. dominate traits mixed with recessive where dominate traits show only vs. pure dominate traits. zygous is 2 of the same traits which could be 2 dominate together or 2 recessive traits together and Heterozygous is where 2 different traits would be together aka dominate and recessive. I am not sure what you mean by the last question though. Possibly you need more information about the D1S80. Hope i helped.
