Traits and Reproduction Review

In which type of reproduction do all of the offspring's genes come from one parent and offspring are identical to the parent?

• Asexual Reproduction

• Sexual Reproduction

Answer explanation

Sexual reproduction involves TWO PARENTS and the offspring are NOT identical (there is variation).

Asexual reproduction involves ONE PARENT and the offspring are IDENTICAL to the parent.
