Zygosity of variants/allele in VCF

Question

[genie66]

I am new to bioinformatics and trying to understand the zygosity of variant/allele in VCF data. Couldn't find proper bioinformatics explanation anywhere, can someone please explain the difference between different zygosities(Hetero,homo, hemi) and these three in terms of compounded, inherited and dominant with simple VCF formatted examples(GT,sample). This would be really helpful for many who are looking to understand zygosity in terms of Bioinformatics. Greatly appreciate any help. Thanks.
