Closed:genotype Varscan2 tumor/normal samples

Question

[noeD]

Hello!

I have a question: I have data from tumor and control samples (exome sequencing). I have used Varscan2 in order to call variants but I didn't understand how it assigned the genotype of tumor and control samples. Below I attach an image of a part of my vcf.

The genotypes that I didn't understand are highlighted in red:

1. why the genotypes of normal sample in chr1 12887054 and 16776770 are 1/1?
2. why the genotypes of tumor in chr1 32120616 and 36212199 are 1/1?

Thank you in advance. Best regards
