Summary Introduction

To predict:

The type of fatty acids in the animal fats, fish and plant fats.

Introduction:

The lipids are the biological molecules, which are soluble in non-polar solvents such as benzene. The lipids consist of phospholipids, glycerides, sterols, waxes, fats, and fat-soluble vitamins. The animal fats are generally solid at room temperature and the plant or fish oil is liquid at room temperature.

Expert Solution & Answer

Explanation of Solution

The fats are the triglyceride molecules which are comprised of three fatty acid chains attached to the glycerol molecule through the ester linkages. The fatty acid chains are the long hydrocarbon chains which may be saturated (lack any double bond) or unsaturated (have double bonds).

The saturated fatty acids in the animal fats are tightly packed; hence they have a higher melting point in comparison to the unsaturated fats. The tight packaging of the saturated fatty acids in the animal fats provides solid structure to it.

The unsaturated fatty acids in the plant and the fish oils have kinks in their structure, which prevent the tight packaging. So the melting point is low. The loose packaging of the unsaturated fatty acids is responsible for the liquid nature of the plant and fish fat.

Conclusion

The presence and absence of the double bond in the fatty acids of the fats are responsible for the solid and liquid nature of the fats. The unsaturated fatty acids cannot be packed tightly. The plant and fish fats have unsaturated fatty acids, so they are liquid at room temperature.

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:
