Identical twins are known as monozygotic twins in terms of medicine or genetics as they arise from the same egg and sperm cell. Although the same genome or DNA shared in to both embryo during development of fetus, epigenetic changes, surrounding, exposures, nutrition influence,imprinting mechanism make them different. This make the different gene expression pattern in identical twins. For a detailed review please read the following review paper(attaching the link).

Is the goal of DNA fingerprinting to identify the DNA sequence of every gene?
false it is to show that no one person can have the same fingerprint as another except twins
What makes alleles of the same gene different from each other?
A gene consists of a specific sequence of bases; variations in that sequence make for a different gene.
Why the chromosomes in twins are the same?
they are not same but similar as they bear alleles of same gene.
A mutation is a change in DNA sequence and what?
gene sequence: DNA sequence ( its the same thing)
What is a form of a gene that has slightly different sequence than other forms of the same gene but encodes the same type of rna or protein?
allele

What are mixed chromosome twins?
A twin gene is called an Allele - One of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
What is the effects of mutation?
A mutation is a permenent in DNA sequence of a gene,mutation in a gene's DNA sequence can alterthe aminoacid sequence of the protein encodedby the gene.
A mutation is a change in a?
gene sequence
Why is it important to know a gene sequence?
what is a practical or clinical use of knowing the base sequence of a gene
Information can not be obtained from the sequence of a gene?
Whether the gene is methylated.
What permanent change in the sequence of DNA in a gene is a?
Basically change in the DNA sequence of a gene is associated with change in the nucleotide sequence which may result in Mutation and may cause loss of function of that particular mutated gene.
