Question

no exchange of genetic material among organisms
sex cells - sperm and egg
offspring are produced by the union of two cells
usually from two different parents
offspring come from one parent only
offspring are identical to the parent
unique offspring has a combination of traits from both parents
no genetic variation in the offspring
offspring are produced from the process of fertilization
single celled organisms
:: asexual reproduction :: sexual reproduction

Explanation:

• Asexual reproduction:
• "no exchange of genetic material among organisms": In asexual reproduction, there is no combination of genetic material from different individuals.
• "offspring come from one parent only": Asexual reproduction involves a single parent.
• "offspring are identical to the parent": Since there is no genetic recombination (as in sexual reproduction), the offspring are clones of the parent.
• "no genetic variation in the offspring": Without the mixing of genetic material (which occurs in sexual reproduction), there is little to no genetic variation in asexual reproduction offspring.
• "single - celled organisms": Many single - celled organisms (like bacteria through binary fission) reproduce asexually.
• Sexual reproduction:
• "sex cells - sperm and egg": Sexual reproduction involves the use of gametes (sperm and egg in many organisms).
• "offspring are produced by the union of two cells": The sperm and egg (two cells) fuse during fertilization.
• "usually from two different parents": Sexual reproduction typically requires genetic contribution from two parents.
• "unique offspring has a combination of traits from both parents": Due to the combination of genetic material from two parents (through the union of gametes), the offspring have a unique combination of traits.
• "offspring are produced from the process of fertilization": Fertilization is a key process in sexual reproduction where gametes fuse.

Answer:

• Asexual reproduction: no exchange of genetic material among organisms, offspring come from one parent only, offspring are identical to the parent, no genetic variation in the offspring, single - celled organisms.
• Sexual reproduction: sex cells - sperm and egg, offspring are produced by the union of two cells, usually from two different parents, unique offspring has a combination of traits from both parents, offspring are produced from the process of fertilization.
