Chapter 12 Digging Deeper: Conceptual Learning Activity Back to Assignment Attempts Average/2 1. Why variation? Meiosis occurs in organisms that reproduce through sexual reproduction. Besides just creating gametes, the process of meiosis is very important to the adaptation and long-term survival of many species. To understand why, consider the following scenario. Imagine you are a field biologist studying one particular species of animal. You are looking at two populations of this animal and notice an interesting fact: One genetic trait is represented by each population. The paragraphs in the boxes below summarize your observations. Southern population In this population, every individual has long fur. All individuals depend on their fur to keep them warm. Northern population In this population, some individuals have long fur and others have a thinner coat made of shorter fur. Comparing these traits between both populations, it appears that the population. 9 has greater genetic variation within the entire Without warming, something changes in the environment of both of these populations. The dimate shifts suddenly, creating hotter weather for longer penods of time. This change puts individuals with long fur at serious risk of overheating. What do you predict will happen? O Since the northern population has greater variation within the population, some individuals will survive while others will die out X

The climate shifts suddenly, creating hotter weather for langer periods of time. This change puts individuals with long fur at serious risk of overheating. O Since the northern population has greater vanation within the population, some individuals will survive while others will die out. O offspring in the southern population will spontaneously have thinner fur O The entire northern population will die out. Grade It Now Save & Continue Continue without saving
