The unpredictable change in the structure or amount of DNA of an organism is known as mutation. The mutation that occurs in the somatic cells does not pass from one generation to the next.

Proteins are the amino acid chains that acquire their biological properties by folding into a unique 3D structure.

Expert Solution & Answer

Explanation of Solution

The ways by which protein acquires new function in the course of evolution are:

1. The combination of the different folding domains leads to the formation of new protein with a different function compared to the native protein. The change of the amino acids folds together in a specified position to form a protein. The alteration in the combination of the folding of amino acids leads to the evolution of a new protein.

2. Mutation and selection of the mutated protein. Mutation in a single amino acid present on the primary structure of the protein will lead to the change in the functioning of a protein. The proteins fold and become functional by the specific bonding between the amino acids. Due to the mutation in the amino acid, the folding of the protein will be affected. This leads to the evolution of new protein function. The mutated protein is selected by the body and it can be inherited by the offspring.

Conclusion

Proteins acquire new functions by combining the different folding domains. They also evolve due to the changes in the amino acid sequences due to mutation and selection process.

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:
