b. because mammary gland cells are only found in females
c. because the egg cell has only a haploid complement of genes, whereas the mammary gland cell has a diploid complement
d. because the egg cell has a diploid complement of genes, whereas the mammary gland cell has a haploid complement
e. because without the mammary gland cell, the newborn clone will have no mammary glands from which to receive nutrition
