4) Fossil records support the lack of evidence of early photosynthetic plants.
That they were probably on land and that they evolved into sea animals or that that mountain used to be an ocean or water source and that it dried up and a mountain grew there. I'm not positive that this is correct though.
Answer:
yxz.
Explanation:
Gene order may be defined as the correct arrangement of the gene according to the gene distance between them. The gene order can easily be calculated by looking the physical distance between the gene.
In the given question, the distance between xy = 6.9, xz= 0.7 and yz = 7.6. The gene yxz follows the order correct order at which the recombination distance of all the genes are satisfied.
Thus, the order is yxz.
When combined the dominant one takes over. Therefore, you see the dominant trait physically, not the recessive one. However, genetically, they are both there.
