The actual meaning of the phrase “Nothing in biology makes sense except in the light of evolution” given by Theodosius Dobzhansky. Introduction: Evolution is a process of natural changes that is occurring in the living world from over thousands of years. The process of evolution is continuous that is going on even now. Considering in human time, the rate of evolution is very slow. It may take a thousand of years for an organism to develop a particular character. Majority of the evolutionary changes takes place for the benefit of a particular species.

To explain: The actual meaning of the phrase “Nothing in biology makes sense except in the light of evolution” given by Theodosius Dobzhansky.

Introduction: Evolution is a process of natural changes that is occurring in the living world from over thousands of years. The process of evolution is continuous that is going on even now. Considering in human time, the rate of evolution is very slow. It may take a thousand of years for an organism to develop a particular character. Majority of the evolutionary changes takes place for the benefit of a particular species.

Expert Solution

Explanation of Solution

Evolution is defined as the changes that take place in an organism over a course of time. It is a slow process that never stops. A large part of evolutionary changes happens for the better adaptation of the species to their environment and their good survival.

Biological studies alone can be explanatory about the working and function of biological organs and pathways. However, only biological studies alone cannot explain the development or origin of any particular organ or biochemical pathway. Origin and development of biological organs and pathways can be understood only by linking their biological studies with the evolutionary studies. This fact was put forward by evolutionary biologist “Theodosius Dobzhansky”.

Summary Introduction

To explain: The way in which evolution unifies the biological sciences.

Majority of the evolutionary changes takes place for the benefit of a particular species.

Expert Solution

Explanation of Solution

Using biological studies, one can determine the makeup and working of different biological organs and biochemical pathways. Biological studies are capable of informing about the “proximate causes” only. They are not capable of amplifying the detailed information about any biological organ, pathway, or behavior of an organism. Evolutionary studies amplify the information and tell about common and differentiating patterns amongst different species for any biological phenomenon. In such a manner, evolution unifies the biological sciences.

Majority of the evolutionary changes takes place for the benefit of a particular species.

Expert Solution

Explanation of Solution

Evolution has indeed very much unified the biological science but there are some other principles that also act as a unifying basis for the biological sciences. Some of these are as follows:

Cell theory:
This theory states that every organism in the living world is made up of one or other type of cells. Living cells can only be formed from the pre-existing cells.
Gene theory:
This theory states that in every living organism, all the information needed for their formation (cell formation) and proper functioning is carried by their genes. This information is called as “traits”. These traits are carried by the genome (DNA or RNA) of that organism and are passed on from one generation to the next.
Homeostasis:
This is the ability of an organism to maintain a stable internal environment irrespective of the external environment. Every organism in the living world performs homeostasis. Process of homeostasis is carried out by different species in a different manner. Some adopt behavioral changes while others change their internal activities.

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:
