Summary Introduction

All materials are made from atoms. More than hundred different types of atom that has chemical and physical properties are called an element. An atom is the smallest unit of an element with distinctive properties. Every atom is made up of a nucleus consisting of neutrons (neutral charge) and protons (positive charge), and negatively charged electrons that surrounds the nucleus.

Expert Solution & Answer

Answer to Problem 1TQ

The number of protons in the atom determines the atomic number of an atom.

Therefore, option (a) is correct.

Explanation of Solution

Justify the reasons for the correct statement:

The number of protons in an atom’s nucleus is referred to as the atomic number. The atomic number of an atom is denoted by the symbol “Z”.

Option (a) is given as “protons”.

Hence, the option (a) is correct.

Justify the reasons for the incorrect statements:

Option (b) is given as “neutrons”.

Neutrons determines the neutrally charged particles in an atom. It does not determines the atomic number of an atom. Hence, it is a wrong answer.

Option (c) is given as “electrons”.

Electrons are negatively charged particles that surrounds the nucleus of an atom. The number of electrons does not determine the atomic number. Hence, it is a wrong answer.

Option (d) is given as, “electrons plus neutrons plus protons”.

Electrons plus neutrons plus protons constitutes an atom, and it does not determine the atomic number. Hence, it is a wrong answer.

Hence, options (b), (c), and (d) are incorrect.

Conclusion

Atomic number of an atom is determined by the number of protons in the atom.

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:
