Fig.1: The major brain regions.

Explanation of Solution

Cerebrum: The cerebrum is the biggest and the most complicated among all the regions and structures of the brain. The cerebrum is divided into the left and right hemispheres. The cerebrum account for higher mental functions, cognitive thinking, and intelligence. The cerebrum accounts for thinking and reasoning to process the information from the surrounding that can implement the desired movement in the skilled skeletal movement.

Cerebellum: The cerebellum is also called as little brain and located inferior to the cerebrum and posterior to the pons and medulla oblongata. The vital functions of the cerebellum are to process sensory information, maintain balance, posture, and aid in the movement of the skeletal muscles in a skillful way. Depending upon the injury in the cerebellum, the person can be paraplegic from the neck to the feet, paraplegic only to the waist, or only below the waist. Some minor injury in the cerebellum can lead to the unsteady gait, loss of coordinated movement, and slurred speech.

Diencephalon: The “di” means two and “encephalon” means the brain, as it is embedded inferior to the two cerebral hemispheres and anterior to the midbrain. Thus, the diencephalon occupies the central region of the brain. The diencephalon contains the thalamus, hypothalamus, and epithalamus, which are important for secreting hormones, process sleep wake cycle, express emotions, and process sensation to eat and drink.

Brain stem: The brain stem has three major regions namely, the pons, midbrain, and medulla oblongata. The brain stem is located posterior to the superior brain region. The brain stem is a vital feature of the brain as it maintains consciousness as well as regulate the sleep cycle. Any injury to the brain stem leads to life-threatening complications.

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:
