Gene families, such as the globin family of genes in primates are the result of: deficiencies inversions simple translocations duplications

The answer is duplications.

Gene family consists of several similar genes. Duplications of single genes, exons, multigene families, or whole genome have given rise to families of related genes. The example is the globin family of genes in primates. About 500 million years ago, a duplication of single globin gene began. Much later, during primate evolution, the additional duplications occurred together with some point mutations. So the end result is diversity in globin chains that arose from original globin gene.

No that answer is wrong. you have written the function of mitochondria in chloroplast and function of chloroplast in mitochondria.
