The answers is simple read it in a book
Gene duplication (or chromosomal duplication or gene amplification) is any duplication of a region of DNA that contains a gene; it may occur as an error in homologous recombination, a retrotransposition event, or duplication of an entire chromosome.
Homologous chromosomes are two sister chomatids stuck together with cohesins forming a tetrad. They have the same genes but not necissarily the same alleles, so they could carry hair color, one with brown the other with blonde. So, homologous chromosomes share the same gene.
What is thediffernece between homozygous and hetrozygous? Homozygous is a gene combination involving two of the same type of allels. AA,hh) hetrozygous is a gene combination involving two different types of alleles (e.g. Hh, Rr)

Chromosomal mutation
gene mutation, chromosomal abberations
a gene is passed on from generations and a chromosome is just found in certain cells
It is caused by a gene mutation in the single gene on chromosome 7 that produces a protein known as CFTR.
tyt
mutation is a permanent change in the DNA sequence of a gene and can alter the amino acid sequence of the protein encoded by the gene..
Neither. It is an extra #21 chromosome.
Yes, it is caused by a mutation in the gene for the protein CFTR.
i] spontaneous mutation ii] induced mutation iii] germinal mutation iv] somatic mutation v] chromosomal mutation vi] gene mutation are the some of the major types of mutation......
There are many thousands of different mutations.
Two types of gene mutations are chromosomal and point mutation. Chromosomal mutation alters a cell's chromosomes, while point mutation replaces single-base pair nucleotides with other nucleotides found in RNA or DNA.
