Answer:
spinach plants will be more genetically diverse than tomato plants because sexual reproduction generates more genetic diversity than asexual reproduction
Explanation:
In nature, there are two basic mechanisms of reproduction: sexual reproduction and asexual reproduction. Genetic variation can be generated by the following mechanisms: mutations, random fertilization, recombination (i.e., crossing over), and the independent assortment of homologous chromosomes during meiosis. Sexual reproduction involves two parents, thereby new genetic variation can be generated in the offspring through all these mechanisms: new mutations, genetic recombination (which generates new alleles within an organism's offspring), random fertilization, and the random (independent) assortment of homologous chromosomes during meiosis (these last two mechanisms can potentially generate new genetic combinations in the offspring). Moreover, asexual reproduction involves a single parent, and thereby in this case genetic variation can be only generated by mutations that are passed on to offspring.

Answer:
The categories of patterns of evolution are: <em>genetics/molecular biology, direct observation of evolutionary change, the fossil record, homology/anatomy, and biogeography</em>
Explanation:
- <u>Anatomy.</u> Also known as Homology, is the study of homologous structures of species with similar physical features, as proof of direct descent and ancestry.
- <u>Molecular biology and Genetics</u>. DNA and the genetic code reflects the shared ancestry of life, indicative of how species are related.
- <u>Fossil Records.</u> Fossils register the existence of pre-existing species which are related to present-day species.
- <u>Biogeography</u>. The geographic distribution of organisms on Earth, as well as their distinct features is an indicator of evolution and geological change.
- <u>Direct observation. </u>Organisms with short lifespan can be observed as evolutionary cases.
