All mutations involve whole chromosomes
Occur only in gametes
Some are visible only under certain conditions
Most are beneficial
Reduced ability to reproduce
Introduction of new genetic material
Weeding out the less fit
Smaller populations
Sometimes only temporary changes if the DNA is repaired
Heritable changes in the sequence of nucleotides in DNA
Heritable changes in DNA that produce an observable change
Mistakes in the formation of proteins
Replacement of the sequence UGU with UGC
Substitution of a single base in DNA
A segment of DNA is lost
All of these
Often expressed as abnormal proteins
Some do not change the sequence of amino acids coded for by the mutated gene
Are usually harmful to the organism
All of these
They are all expressed, but under different circumstances
Very few are actually expressed
They are either expressed during all life stages or not at all
Some are expressed constantly and others infrequently
