Question

What will happen :
when a part of the chromosome breaks and attaches to another homologous chromosome.

Answer 1

Mutations are defined as sudden stable discontinuous and inheritable changes which appear in the organism due to the permanent change in the genotype. A genetic mutation normally alters information conveyed by a gene that alters the messages. Chromosomal mutation only alters the number of position of existing genes. They may involve modification in the morphology of chromosome for a change in the number of chromosomes. When deleted chromosome segment is attached to its normal homologous chromosomes it causes duplication. Here some genes or many genes are replicated twice or more times in the same chromosome and this is known as duplication.
