a. Why does syphilis have such profound effects on the human body?

b. Why is long-term immunity to syphilis so difficult to achieve?

Expert Solution & Answer

Summary Introduction

To determine:

Why syphilis has such profound effects on human body and why is it difficult to achieve long-term immunity to it.

Introduction:

Syphilis is caused by the spirochete Treponema pallidum. It is a strict parasite that has complex growth requirements and this necessitates cultivating them in live cells.

Explanation of Solution

Humans act as sole natural host for the parasite. It is an extremely fastidious and sensitive parasite that cannot survive outside the host for long time and is rapidly destroyed by heat, drying, disinfectants, and other adverse conditions. It is transmitted sexually. Hence, it has such profound effects on human body. Protective immunity does not arise in case of humans against the syphilis pathogen and this makes vaccination difficult. Hence, long-term immunity to it is difficult.

Conclusion

Hence, it may be concluded that, humans being the sole host for parasite, syphilis has profound effect on humans and the ability to obtain protective immunity against it makes long-term immunity difficult.

Three of the many recessive mutations in Drosophila melanogaster that affect body color, wing shape, or bristle morphology are black (b) body versus grey in wild type, dumpy (dp), obliquely truncated wings versus long wings in the male, and hooked (hk) bristles versus not hooked in the wild type. From a cross of a dumpy female with a black and hooked male, all of the F1 were wild type for all three of the characters. The testcross of an F1 female with a dumpy, black, hooked male gave the following results: Trait Number of individuals Wild type 169 Black 19 Black, hooked 301 Dumpy, hooked 21 Hooked, dumpy, black 172 Dumpy, black 6 Dumpy 305 Hooked 8 Determine the order of the genes and the mapping distance between genes. Determine the coefficient of confidence for the portion of the chromosome involved in the cross. How much interference takes place in the cross?

Genes at loci f, m, and w are linked, but their order is unknown. The F1 heterozygotes from a cross of FFMMWW x ffmmww are test crossed. The most frequent phenotypes in the test cross progeny will be FMW and fmw regardless of what the gene order turns out to be. What classes of testcross progeny (phenotypes) would be least frequent if locus m is in the middle? What classes would be least frequent if locus f is in the middle? What classes would be least frequent if locus w is in the middle?
