Factors b,d,e,g are favorable to fossil formation and preservation.
<span>Hard bodies are more easily preserved; rivers and oceans deposit muds that keep bodies intact for long times after death; large population and long existence provide more opportunity for fossils to form; and a low oxygen content impedes decay and inhibits predators. </span>
<span>Factors a,c,f,h are unfavorable to fossil formation and preservation. </span>
<span>Thus, Organism E with 4 positive factors is number 1 -- has the top chance of forming a fossil. </span>
<span>Organism D with 4 negative factors would be number 5 -- has very little chance of forming fossils. </span>
<span>Of the other 3, all have soft bodies, so are "disadvantaged" compared to E...but </span>
<span>Organism A has no OTHER disadvantages, so is probably number 2 (second best fossil chance). </span>
<span>Organism C has ALMOST everything going against it -- despite its large population and long existence, it has no other positive factors -- so I'd put it at number 4 (second worst). </span>
<span>To summarize, my rankings are </span>
<span>1. E, 2. A, 3. B, 4. C, 5. D</span>
Peer review and reapeted experimental values. Please tell me if this helps you.
Answer:
The percentage of recombinants = (59/643) ×100 = 9.1%. Thus, the two genes are 9.1 mu or 9.1 cm apart.
The percentage of palatals = (584/643) ×100 = 9.1%. Thus, the two genes are 90.8 mu or 90.8 cm apart.
