Introduction:

Meninges is the protective layer that envelops the brain and spinal cord. It is a three-layered structure. The layers of meninges include an outer layer, a middle layer. Another innermost layer is also present. Subarachnoid space implies the area below the arachnoid region.

Expert Solution & Answer

Answer to Problem 1DYKB

Correct answer:

The correct answer is option (b) Pia mater.

Explanation of Solution

Explanation/justification for the correct answer:

Option (b) Pia mater. Te deep or the inner layer of the meninges is the pia mater. The subarachnoid space lies between the arachnoid region and the pia mater.

Explanation for incorrect answer:

Option (a) Arachnoid mater. It is one of the three layers of the meninges. It is not the deepest or innermost layer and it lies above the subarachnoid space. Hence, this is an incorrect answer.

Option (c) Dura mater. It is the first and the outermost layer of the meninges. Hence, this is an incorrect answer.

Option (d) It is the region that lies below the dura mater. It is not the inner layer of the meninges. Hence, this is an incorrect answer.

Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…

Question #5: Assume that two genes are identified that confer gametophytic facultative apomixis in soybean. The genes show independent assortment. Recessive alleles at both loci are required for the facultative apomixis. Facultative apomixis is triggered when the temperature at pollination is above 20 degrees C. At temperatures below 20 degrees C, all reproduction is sexual, independent of genotype. A facultative apomict male, capable of producing viable pollen, was crossed with a sexually reproducing female. Assuming the parents are completely inbred, what are the predicted phenotypic ratios (apomict: non-apomict) for the F1, F2, and DH (F1-derived) generations at each of the following temperatures*: a) 15°C? b) 25°C? *for full credit, show crosses and genotypes where appropriate. Remember to position the female first (left side) in the cross. Type your answer here:
