What genes are inherited from mother only?
And, mitochondrial DNA (or mDNA) is inherited strictly from the mom. Because mDNA can only be inherited from the mother, meaning any traits contained within this DNA come exclusively from mom—in fact, the father’s mDNA essentially self-destructs when it meets and fuses with the mother’s cells. Sorry, male DNA!

Are brown or green eyes more dominant?
The different variants of genes are referred to as alleles. … The allele for brown eyes is the most dominant allele and is always dominant over the other two alleles and the allele for green eyes is always dominant over the allele for blue eyes, which is always recessive.
