PPT-Evidence for Human Variation and Adaption

Venessa Williams Hai Tran Myles Everett Alex Detlefsen Bio 1510A Group A39 September 13 2012 Introduction Little known about genome sequences of Africans Common ancestors 1000 Genomes Project used new technology to view whole genome sequences. Goal: Use inverse variation and joint variation models.. Warm-up. Simplify:. Inverse Variation. 2 variables, x and y, vary inversely if:. k is called the constant of variation.. Example 1. Tell whether x and y show direct variation, inverse variation, or neither:. Jeff Barrett. What are the goals of disease genetics?. For a given disease, we would like to:. Predict if someone will get sick, how bad it will be, and what treatment will work.. Test hypotheses about relationships to other diseases and traits.. Image from about.com . meiosis_metaphase_1.jpg. . Mutations. (changes in an organism’s DNA) are the . original. . source of . all. genetic variation. Mutations create different versions of genes called . What do you mean by variation..?. Differences between species. Differences within a species. SPECIES : . A . species.  is a group of organisms that are able to interbreed and produce . fertile.  offspring.. Define the term variation.. Discuss the fact that variation occurs within, as well as between, species.. Describe the differences between continuous and discontinuous variation, using examples of a range of characteristics found in plants, animals and other organisms.. Liz Cirulli. Assistant Research Professor. Duke Center for Applied Genomics and Precision Medicine (CAGPM). 4/27/15. Advantages to studying healthy variation. Most “healthy” traits not studied genetically at all. y = . kx. , where k ≠ 0. . The constant of variation for a direct variation . k. is the coefficient of . x.. Example of direct variation. : The time it takes to hear thunder varies directly with the distance from lightning. (As the distance from lightning increases, so does the time it takes you to hear the thunder!). 1. Attributes of Common Cause Variation. It is the variation inherent to a Process.. It cannot be reduced unless one changes the Process.. It can be considered to be the background noise present in a Process.. ANGGOTA KELOMPOK. SRI YUNIARTININGSIH (P2BA10009). YAYUK SUGIYARTI (P2BA10025). IHDA SYFAI (P2BA10010). Origins of Genetic Variation Among Offspring. The behavior of chromosomes during meiosis and fertilization is responsible for most of the variation that arises in each generation. Sexual and asexual reproduction. Reproduction. advantages/disadvantages. Sexual. Asexual. Needs two parents.. Only one parent needed (quicker).. Produces variation in the offspring.. Identical offspring (no variation).. By exploring the characteristics offspring inherit when living things reproduce, I can distinguish between inherited and non-inherited characteristics.. SCN 2-14b. Learning intentions. Identify some of the differences between people.. Peter van . Bodegom. Department of Systems Ecology. VU University Amsterdam. The Netherlands. Traits vary considerably within and between communities. Kattge. et al. 2011 GCB. Traits also tend to respond to climate manipulations. Mississippi:. Genetics . vs . Nutrition. Steve Demarais. Regional . Antler Size Variation. @ 5+ Years. (Harvested Bucks). Delta. Loess. LCP. Coast. 20“. (Strickland and Demarais 2000). Regional Body. Biology Trending, 4e. Eli Minkoff and Jennifer Hood-DeGrenier. There is biological variation both within and between human populations. Continuous and discontinuous variation within populations. Variation between populations.
