Expert Solution & Answer

Summary Introduction

Archaea and bacteria are referred to as prokaryotic unicellular organisms. Initially, archaea were classified as bacteria, thereby receiving the name archaebacteria. Since 1960s, genetic, biochemical, and genomic analyses are combined with developed methods for archaeal and bacterial cell imaging. As a result, it was concluded that Archaea and Bacteria are belongs to different taxa.

Explanation of Solution

Archaea and bacteria are referred to as prokaryotic organisms. Based on morphological features, they seem to be the same taxonomic group. However, based on genomic analysis, it was revealed that both organisms belong to different domains. In 1977, the American biophysicist and microbiologist revealed the third domain of life, which is known as archaea. This is achieved by the analysis of phylogenetic taxonomy of 16S ribosomal ribonucleic acid (rRNA).

The other features that reveals that they are belonged to different domain are as follows:

The plasma membrane of archaea is made up of strikingly different lipids compared to those present in the plasma membrane of bacteria. The bacterial plasma membrane is comprised of ester-linked phospholipids like hapanoids and sterols, whereas the archaeal plasma membrane is comprised of diether glycerol or tetraether glycerol. Secondly, the cell wall of archaea is diverse compared to bacterial cell wall. This is because; the cell wall of archaea lacks peptidoglycan whereas the bacterial cell wall is made up of peptidoglycan.

Therefore, the above explained differences made this statement to disagree. Hence, archaea should be separated from the bacteria.

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:
