If the mutation takes place in a gamete that ends up forming an embryo, the mutation will be passed on to an offspring. This can also occur if the mutation occurs early in an embryos development, and the cell becomes one of the gamete forming cells, the mutation will be passed on to their offspring.

Answer:
Average atomic mass = 21.38 amu.
Explanation:
Given data:
Mass of first isotope = 21 amu
Abundance of first isotope = 62%
Mass of second isotope = 22 amu
Abundance of second isotope = 38%
Average atomic mass = ?
Solution:
Average atomic mass  = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)  / 100
Average atomic mass  = (62×21)+(38×22) /100
Average atomic mass =  1302 +836 / 100
Average atomic mass = 2138 / 100
Average atomic mass = 21.38 amu.
