  In animals, polyploidy is not tolerated and very few polyploid species
  are known to exist. Those that do exist are usually asexual,
  parthenogenetic, or hermaphroditic. Most of the problems resulting
  from polyploidy occur during synapsis of homologues during prophase I.
  
  As plants do not have a chromosomal mechanism for sex determination,
  synapsis and subsequent disjunction is not as great a problem. In
  fact, most plants are monoecious.


These paragraphs are taken from these lecture notes from an Emporia State University genetics course.

Supporting information looks to be present in Why Polyploidy is Rarer in Animals Than in Plants (H. J. Muller, The American Naturalist, 1925), but I didn't get a chance to access the article.

Why is polyploidy lethal for some organisms while for others is not?
In our field we continue to sell our product in terms of better user experience, easier to complete tasks, less pressure on user and so on. We do that being convinced that it benefits our customers and employers. This is great, because we make the digital world better and easier and more joyful.

Marketers also sell products and solutions to company to solve problems and issues. They too have a vision and a concept of a better digital world, but from a different facet. I’m often stunned by how they accomplish tasks and gain rightful trust by the customers.

Sometimes marketers and user experience experts are colliding; sometimes they work side by side in collaboration. But from a general notice – which marketing activity gets the best conversion rate marketing or UX? Does a dollar spent on UX make more ROI than a dollar spent on marketing?
