Question
Chapter 5, Problem 2ER
Summary Introduction
To describe: What is clinal variation.
Introduction: The Bergmann’s rule indicates that as latitude increases, the breadth of the body also increases. Skin pigmentation is an example of clinal variations. From higher latitude to equatorial, the skin color between people is widely varied from dark to light.
Summary Introduction
To identify: Two physiological effects of solar radiation that acted as a selective pressure in shaping the clinal variation pattern to observe human skin color.

The skin pigment melanin is expressed differently according to exposure to sunlight, with a greater production of the molecule with greater exposure. However, the degree of production can never exceed the inherited genetic level. What evolutionary advantage would be gained from having this phenotypic range for skin pigmentation?
What is the difference in the studied skin color gene between dark skinned and light skinned people?
Regarding albinism, name and briefly describe diagnostic procedure(s) that can be used to detect the defective gene?

Explainarrow_forwardHair color is due to the presence of melanin. There are two types of melanin produced by melanocytes. One is eumelanin, which is responsible for black (homozygous), brown (heterozygous), and blond (recessive) hair colors. The other is pheomelanin, which is responsible for red hair color. During melanin synthesis, MCR1gene converts pheomelanin to eumelanin. However, a variant of the MCR1 gene (MCR1variant), prevents this conversion. A cross between a blond-haired mother and a red-haired father produced 100% brown-haired children. When they came of age, one child married a double heterozygote, and both were blessed with 7 children; 2 with black hair, 2 with brown hair, 1 with blond hair, and 2 with red hair. TIP: Black hair is homozygous while brown hair is heterozygous, thus represented together in determining the ratio and written as black/brown in the 9:3:3:1 ratio. However, all F2s must be given their COMPLETE genotypes. Using the 7-step method, determine the genotypes of the…arrow_forward

Darker skin is usually found in high UV areas while lighter skin is usually found in low UV areas D.

- Neurofibromatosis type 1 (NF1) is an inherited is an inheritent dominant disorder. The phenotype usually involves the production of many skin neurofibromas. Answer the following question about the disorder: The rarer form of neurofibromatosis is called segmental neurofibromatosis. In this form of the disease, neither parent of the patient has any clinical sign of the disease, and the tumors in the patient are restricted to one part of the body. Suggest an explanation for the genesis of segmental neurofibromatosis that clarifies why it is restricted to one part of the body.arrow_forwardDefine the term Dilatation?arrow_forwardAbout 9 percent of Caucasian males are color-blind andcannot distinguish red-colored from green-coloredobjects.a.
