Question

Some genes don’t appear to have any mutations associated with them. Why do you think this is?

Answer 1

• gene are the inheritance unit, which is transferred from one generation to other
• the gene for an individual get from father and mother
• there are some genes which are getting from mother only while others are combination of the both so there are chance for wide variety of genes for a trait can appear, this cause change in he characters of individual different from that of parents
• mutation can occurs in any one of the genes, it may affect the normal functioning of the genes for the expression of the character , but a trait is expressed by two gens so if there is mutation in one other will be normal itself
• this normal allele is able to express its trait, if it is dominant gene but if it is recessive there can be mutation change
• dominant gene can function normally as other normal allele this make as feeling that there is no mutation associated with this gene
• so this mutation does not cause any effect on the gene expression
• but this only occur in those genes which are dominant, because of their masking ability
• so only some genes don't appear to have any mutation associated with them
