Answer:

are the source of new genetic variation

Explanation:

The concept of mutation is related to the modification of genetic material. Any kind of change, be it in the organization or in number, will result in a new genotype and character.

The importance of mutation lies in the fact that it is precisely that that guarantees the modifications of species, since it is only through a mutation that new genes can emerge. This is why mutations are important and considered the basis for the evolution of species in all populations.

3. (b) How does crossing over increase the variation in the gametes (and hence the offspring)?
sasho [114]

Answer:

During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material. Gametes gain the ability to be genetically different from their neighboring gametes after crossing over occurs.

The lead exposure can cause the abnormal development of brain and damages the brain of fetus. The fetus has low birth weight also.

Thus, the correct answer is option (3).
