Do you think animals pollinate flowers and disperse seeds on purpose or by accident?
Allushta [10]

Answer:

Animals most likely pollinate by accident.

Explanation:

Deer for example, they may graze in the grass. The pollen/seeds could catch onto their fur--and later fall off into a different area when they walk away. They could also eat a plant, and the seeds end up in their feces. Bees for another example don't necessarily <em>mean</em> to pollinate, they just happen to pick up pollen/seeds when they land on a flower for honey.

Hope this helps :)

fredd [130]

Answer:

the pleiotropy and epistasis (more info below)

Many human traits have dynamic forms of ancestry. We can be regulated by a single gene with several alleles, or by several genes. Further complication can be added by pleiotropy (one gene, multiple effect) and epistasis (gene-gene interaction). A number of hereditary diseases are triggered by defects in one or a few genes. examples: autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive, and mitochondrial.
