Macroevolution is distinct from microevolution in that macroevolution

a.	results in changes to life’s diversity.
b.	results in changes to the DNA of organisms.
c.	affects larger organisms.
d.	can be observed.

Expert Solution & Answer

Summary Introduction

Introduction:

The types of organisms have changed throughout the history of life. New species have appeared, and many have gone extinct. These events are included in evolution. Evolution is of two types: macroevolution and microevolution.

Answer to Problem 1MCQ

Correct answer:

The appearance of new species and the extinction of species are studied under evolution. These large and complex changes in life’s diversity are known as ‘macroevolution.’ Hence, the correct answer is option a.

Explanation of Solution

Reason for correct answer:

Option a. is given as, “results in changes to life’s diversity.”

Macroevolution is distinct from microevolution. As the name suggests, it describes the large changes in organisms such as the appearance of new species. Macroevolution eventually results in large scale changes in life’s diversity, which includes extinction and appearance of new species.

Reason for incorrect answer:

Option b. is given as, “results in changes to the DNA of organisms.”

The changes in DNA or shifting of allele frequencies in organisms represent small scale changes in the population which result in microevolution. Hence, option b. is incorrect.

Option c. is given as, “affects larger organisms.”

Macroevolution affects the population with large changes which includes all organisms. It does not affect only large organisms. Hence, option c. is incorrect

Option d. is given as, “can be observed.”

The process of macroevolution takes places only at species level due to which it cannot be observed or detected easily for different species. Hence, option d. is incorrect.

Hence, the options b., c., and d. are incorrect.

Conclusion

Macroevolution is distinct from microevolution, which results in large and complex changes to life’s diversity. Thus, the correct answer is option a.

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:
