HS-LS3-3 Inheritance and Variation of Traits Variation & Distribution, applying concepts of statistics and probability to explain the variation and distribution of expressed traits in a population.
Lesson Brief:
Traits within a population vary around the average value. Probability can be used to understand this variation. Variation within a population is necessary for natural selection to occur as it allows for different reproductive success, or genetic fitness, based upon the traits. In this activity we will examine how variability occurs and how this variation in the value of a trait takes on a predictable statistical distribution.
