Answer:
c. Would have deviated from the 9:3:3:1 phenotypic ratio
Explanation:
<em>If two genes are linked together on the same chromosome, the phenotype of the F2 generation would have deviated from 9:3:3:1.</em>
Two genes whose loci are close on the same chromosome are said to be linked. Linked genes have higher frequency of recombination than genes that are not linked.
<u>Hence, while genes that are not linked assort independently to produce 9:3:3:1 phenotypic ratio at F2, linked genes do not assort independently and the higher frequency of recombination ensures that they standard phenotypic ratio is deviated from.</u>
The correct option is c.
Answer:
b. characterized by a lucid interval immediately after injury.
Explanation:
Epidural bleeding is the accumulation of blood between the dura (membrane lining the brain) and the skull. This bruise is typically caused by an acute head trauma that ruptures the middle meningeal artery. This bleeding is characterized by a lucid interval immediately after an injury to this region.
This bleeding has its most frequent location at the temporal lobe level, between the bone and the dura mater. It is due to rupture of the middle meningeal artery, usually by a temporal bone fracture. The artery runs on the outer surface of the dura, housed in a groove in the inner bone board. The fracture may clamp or cut the artery, leading to a bruise.
I'm pretty sure that it's C. I'm not quite sure though.
