Summary Introduction

Introduction:

Skin is a flexible and tough outer membrane, also known as cutaneous membrane. Skin contains numerous physical and chemical properties that makes it an important barrier against destructive pathogens. It restricts infection and disease unless it has been cut or broken. Cutaneous mycosis is a skin disorder which is caused due to fungal infection.

Expert Solution & Answer

Answer to Problem 1MCQ

Correct answer:

An effective treatment for a cutaneous mycosis like tinea pedis would be miconazole. Therefore, option (b) is correct.

Option (b) is given as “miconazole”.

Explanation of Solution

Justify reasons for the correct statement:

Cutaneous mycoses generally called as ringworms, which are caused by a group of fungi collectively called dermatophytes. These mycoses mainly attack on the non-living epidermal tissues and their derivatives. All the conditions associated with these mycoses begin with the word ‘tinea’. Tinea pedis is a condition associated with the infection of foot. The effective treatment of tinea pedis includes the use of ointments containing miconazole, tolnaftate, itraconazole, and so on.

Hence, option (b) is correct.

Justify reasons for the incorrect statements:

Option (a) is given as “penicillin”.

Penicillin acts as an antibiotic and it is used to treat infections caused by bacteria. Tinea pedis is a fungal infection. Hence, it is a wrong answer.

Option (c) is given as “griseofulvin”.

Griseofulvin is used to treat nail and skin infections caused by fungus, but not fungal infections associated with foot. Hence, it is a wrong answer.

Option (d) is given as “doxycycline”.

Doxycycline is also used as an antibiotic to treat bacterial infections. Tenia pedis is a fungal infection. Hence, it is a wrong answer.

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

Conclusion

Tenia pedis is included under cutaneous mycoses, and it is treated effectively with miconazole.

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:
