Question

genetic diversity comes from two main sources. the ultimate source of new alleles is genetic. in which rare changes in dna may produce a new protein and possibly a new trait. another source of genetic variety is genetic. which occurs when alleles are redistributed in eggs and sperm, sometimes leading to the production of offspring with new traits.

Explanation:

Genetic mutations are changes in DNA that create new alleles. Genetic recombination occurs during meiosis when alleles are shuffled in gametes (eggs and sperm), leading to new trait combinations in offspring.

Answer:

mutation; recombination
