Phenotypes are characteristics of an organism which we notice through different physical features such as hair color, body weight, capabilities, the way someone might behave, etc. Variation is the differences in an individual in the population, Variation plays an important role in phenotype because it helps us understand life., we see a variety of attributes everywhere each one mirrors an alternative important reason. For example, a bear and a fox are completely different from each other however two animals that are from the same species have little differences. Another example will be twins who share same genotype however environmental factors make them different. This is because phenotypes are …show more content…
Every organism gets these genotypes from our parents. This is of course a huge contribution to phenotypes in variation in our population. to study because will help us study evolution. It also helps us study heritability. Geneticists have done study on identical twins even though they share the same genotype sometimes environment might be different. Geneticists often study adoptive siblings because genotypes highly differ, and environment is the same. Obesity is a variation in our population that is affecting more than 35 percent of our population in United states. Obesity runs in many families which can bring about many health problems such as heart conditions, cardiovascular diseases, pulmonary diseases and other health problems such as diabetes. Phenotypic Variation helps us study intelligence or IQ many scientists in the past believed that IQ comes only from genetic influences. IQ tests have shown that scores have something to do with an individuals race. For example, African Americans scored 15 points lower than the average white. Variation in phenotypes can help scientist figure out why some races score much lower than their other counterparts. Phenotype Variations can also help us study chromosome
