The more admirable twin is said to be the right-handed one. You can infer from this that Iroquois appreciate honesty.
What do you mean by twins?
Twins are two children born from a single pregnancy.
Twins can be monozygotic (also known as "identical"), in which case they arise from a single zygote that divides into two embryos, or dizygotic (also known as "non-identical" or "fraternal"), in which case they arise from distinct eggs, each of which is fertilized by a different sperm cell.
Identical twins share the same sex because they are created from a single zygote, whereas fraternal twins may or may not.
Rarely, twins may have separate fathers and the same mother.
