Which of the following structures is identical in monozygotic twins?

Which disease is caused by an $X$-linked recessive gene but is not lethal?

Genes that are similar in phenotypic effect when present separately,but together interact to produce a different trait and the ratio is $9:7$ in the $F_2$ generation. What are such genes known as?
