Somatic mutations lead to cancer or other disease in the affected individual ONLY D. Germ line mutations lead to cancer or other disease in the affected individual ONLY E. Germ line mutations lead to changes in fitness for the affected individual ONLY OF. Somatic mutations lead to changes in fitness for the progeny OG. Germ line mutations lead to changes in fitness for the progeny OH. The impact of a mutation is dependent on selective pressures 1. Germ line mutations lead to generation of new alleles that are passed on to the progeny J. Somatic mutations lead to generation of new alleles that are passed on to the progeny OK. Somatic mutations lead to changes in fitness for the affected individual ONLY

Answer 1

Answer: C, G,H,I and K

Mutations are not always beneficial or detrimental ( harmful) .They can either be beneficial,harmful or neutral .The impact of mutations depends on selective pressures to determine whether the mutations should be beneficial or harmful to the present environment.

Somatic mutations occurs in any part of the body other than germ cells ( cells after full development become egg and sperm) so it will not be passed on to progeny or offspring .It cause cancer or any disease in the affected individual only.

Germline mutations occurs in germ cells( egg and sperm) so it will be passed on to the progeny or offspring .It leads to generation of new alleles that are passed on to the progeny .
