Summary Introduction

To review:

Whether mother and daughter cells are genetically identical when they areformed by binary fission.

Introduction:

The process of reproduction in which offspring are produced by a single parent or a single organism where there is no need forfusion of the gametes, is known as asexual reproduction. Asexual reproduction mainly takes place in single-cell organisms, such as algae, bacteria, and fungi.

Explanation of Solution

Binary fission is the method of asexual reproduction in prokaryotes, through which new organisms are produced, that are genetically identical to the parent organism.In the process of binary fission, the DNA (deoxyribonucleic acid) within the cell is replicated, the copies then slide to opposite terminals of the cell in an energy-dependent process.

The cell elongates and equatorial plane of the cell contracts, whichsegregates the cell’s plasma membrane, following which, new cells are generated which constitute exactly the same genetic material.Thus, daughter cells are generated from a single parent cell and have same genetic material as well as cell components, so, theyare genetically identical. However, they are identical when the mutations are not considered.

Conclusion

Therefore, it is concluded that mother and daughter cells are genetically identical when they are generated by binary fission because they shareidentical copies of genetic material from a mother cell, provided that the mutations did not take place during replication.

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:
