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.

Answer: The protein is completely disrupted and it can not perform its function
Explanation:
Tay-Sachs disease is a rare degenerative disease and autosomic recessive. It affects the brain and central nervous system. It occurs when the body lacks hexosaminidase A, which is a protein that helps break down a group of chemicals found in nerve tissue, called gangliosides. Without this protein, gangliosides build up in cells, often in neurons in the brain.
Tay Sachs disease is caused by a mutation of one nucleotide for a protein that disrupts the activity of an enzyme in the brain. Proteins are synthesized according to the DNA sequence. Every three bases (called a codon), one of the many amino acids that will form the protein is synthesized. When one of these bases is mutated, it is very possible that a different amino acid is synthesized instead. Sometimes that doesn't happen because the genetic code is degenerated and different codons can give rise to the same amino acid. But in this mutation, the protein is completely disrupted and it can not perform its function. <u>Then, the brain is affected as it was explained and results fatal.</u>
