Analyzing the Effects of the Environment on Traits
Student Guide
XEdgenuit
Purpose
In this assignment, you will apply concepts of statistics and probability to answer questions about how
environmental factors affect the variation and distribution of expressed traits in a population.
Background Information
Genetic and environmental factors affect which traits are passed on from parent to offspring over
generations and how they are passed on. Favorable traits for a given environment are passed on from
parent to offspring. Unfavorable traits are selected against and inherited less frequently over time
because they do not promote survival and reproduction,
Assignment Instructions
in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
Answer from: Quest
the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to determine the size of a population.
