Question

New alleles can be created in all of the following ways, EXCEPT by
A) removing a DNA base at a point in the gene.
B) the addition or removal of a chromosome by a meiosis error.
C) substituting a DNA base at a point in the gene, with a different one. D) mixing segments of the same gene, from two parents, during crossing-over in meiosis.

Answer 1

New alleles can be created by

a) removing a DNA base at a point in the gene

b) substituting a DNA base at a point in the gene, with a different one

c) mixing segments of the same gene, from two  parents, during crossing-over in meiosis.

Alleles cannot be created  by the addition or removal of a chromosome by a meiosis error.

Answer 2

New alleles can be made in the expansion or expulsion of a chromosome by a meiosis blunder.

At times, DNA transformations happen in germ cells – cells bound to end up eggs or sperm.

For this situation, the DNA transformation is duplicated into each new cell of the developing incipient organism following preparation.

Along these lines, new DNA variations are passed on to the people to come.
