According to the video “The Biology of Skin Color”, why is lighter skin needed in areas closer to the north and south poles where UV rays are weaker? A. Individuals with a lot of melanin would get too much UV ray penetration in their skin and they wouldn't be able to synthesize vitamin D. B. Lighter skin is not necessary in the north and south poles. C. Individuals with a lot of melanin wouldn't get enough UV ray penetration in their skin to synthesize vitamin B. D. Individuals with a lot of melanin wouldn't get enough UV ray penetration in their skin to synthesize vitamin D.
Figure 1. Ultraviolet Radiation Index across the World. The colors on this map of the world represent Ultraviolet (UV) Index values on a particular day in September 2015. The UV Index is a standardized scale of UV radiation intensity running from 0 (least intense) to 18 (most intense). The y-axis values are degrees of latitude, which range from the equator (0°) to the poles (90° north and −90° south). The x-axis values are degrees of longitude, which range from the prime meridian (0°) to the antemeridian (180° east and −180° west). (Source: European Space Agency,http://www.temis.nl/uvradiati on/UVindex.html.) I. Examine Figure 1 above and answer Questions 1–6. 1. Describe the relationship between the UV Index (the colored bar in Figure 1) and latitude (y-axis). 2. How do you explain the relationship between the UV Index and latitude? (In other words, why does UV intensity change with latitude?) 3. Find your approximate location on the map. What is the primary UV…

In 2011, the population of the world was estimated to be about 7 billion. How many people in the world could theoretically have the same DNA fingerprint?
According to the video “The Biology of Skin Color”, how does UV exposure vary throughout the world? A. The UV rays are the same at the equator and the earth's poles B. There are higher UV rays near the equator and lower UV rays towards the north and south poles C. UV rays don't vary across the globe D. There are lower UV rays near the equator and higher UV rays towards the north and south poles
99.9% of our DNA is the same across all humans worldwide. True or false?
Sixteen percent of a population is unable to taste the chemical PTC. These non-tasters are recessive for the tasting gene. What percentage of individuals in the population are tasters? ______________ What is the frequency of the dominant and recessive allele? _____________________________ What percentage of the population are heterozygous for the trait? ___________________
An anthropologist discovered that Papa new Guyana tribes that had given up the customs of cannibalism also had an avid aversion to grapefruit . The ability to taste the horridbitterness of PTC present in grapefruit respectively human brain tissue is due to a dominant alial. A small tribe of 637 Papa New Guinea hens was tested by a population geneticists the following results were displayed. Tasters Non-tasters Total Males 171 86 257 Females 337 43 380 Total 508 129 637 A.)Calculate the recessive ally of frequency (i)among males (ii) among females B.) calculate the amount of individuals being homeless sigus for tasting PTC, also the number of heterozygotes individuals and non tasters within the tribe. C.) another tribe still being cannibals trust past the territory of the other tribe they were captured killed and feasted on the brains of 50 PTC tasting males respectively 19 females as to access their abilities seen as a gift from gods.…
Data Analysis Activities Neanderthal Hair Color The MC1R gene regulates pigmentation in humans (Sections 13.5 and 14.2), so Loss-of-function mutations in this gene affect hair and skin color. A person with two mutated alleles for this gene makes more of the reddish melanin than the brownish melanin, resu.lti.ng in red hair and pale skin. DNA extracted from two Neanderthal fossils contains a mutated MC1R allele that has not yet been found in humans. To see how the Neanderthal mutation affects the function of the MC1R gene, Carles Lalueza-Fox and her team introduced the allele in to cultured monkey cells (FIGURE 26.12). FIGURE 26.12 MC1Ractivity. Activity is shown in monkey cells transgenic for an unmutated MC1R gene, the Neanderthal MC1R allele, or the gene for green fluorescent protein (GFP). GFP is not related to MC1R. How did MCR1 activity in monkey cells with the mutant allele differ from that in cells with the normal allele?
