Answer;

-No more; no more

Compared with fraternal twins, identical twins are no more similar in physical appearance. Compared with unrelated look-alike pairs of individuals, identical twins report no more similar personalities.

Explanation;

-Compared with fraternal twins, identical twins are much more similar in extraversion, neuroticism and temperament.

-Since fraternal twins are 2 separate fertilized eggs, they usually develop two separate amniotic sacs, placentas, and supporting structures. Identical, or monozygotic, twins may or may not share the same amniotic sac, depending on how early the single fertilized egg divides into two.

d. More; More

Explanation:

Fraternal twins are dizygotic twins that are produced when two independent secondary oocytes are fertilized by two different sperms. These fertilized eggs are implanted in the uterus at the same time and hence, the twins are of the same age but are genetically dissimilar.

Identical twins are the monozygotic twins and develop when the single fertilized ovum develops into two embryos. Identical twins share the same genetic material and have a similar physical appearance and more or less same personality traits.
