Bioc14: w6l5 genetic engineering; linking genetically defined neurons to behaviour i. e. , mendelian patterns of inheritance. Both genetic and environmental differences result in phenotypic variation that looks like a bell shape. Experimental evidence along with statistical analysis is used to determine the portion of variation that is due to genes or environment. Quantitative genetics: field of study that deals with studying quantitative traits (statistical approach is a major part) But it"s not the same as inheritance per se. Xi is the ith data point n is the number of data points. Variance: degree of variability in a group i. e. , spread of numbers larger the value, bigger the spread. The model assumes that the variation is the same on either side of the mean. As a result, there is a bell- shaped curve: in reality, this might not always be the same where the variation is the same on either side of the mean.
