Which type of mutation occurs in reproductive cells and can be passed to offspring: ? a. somatic mutationb. germline mutationc. point mutationd. frameshift mutation

The answer is B. germline mutation. 

The germline mutation is heritable variation in the lineage of reproductive (germ) cells. Germ cells are cells that give rise to the gametes, so a mutation in germ cell will be seen in a sperm cell or egg cell but not in a skin cell, for example.

The point mutation is the changes in a single nucleotide base on the DNA molecule.

Frameshift mutation, due to addition or deletion of a base, results in the change of reading frame and totally different translation

Somatic mutation is mutation in a somatic cells and is not passed on to the next generation. 

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
