Traits are passed from parents to offspring through genes. This variation results from random mutations and genetic recombination. Mice inherit their fur color alleles from their parents. ifferential Survival & Reproduction
The environment "selects" for favorable traits. In our beetle example, if the environment is a brown forest, brown beetles will be better camouflaged from predators than green beetles. Consequently, brown beetles survive and reproduce more often. This pressure drives populations in different directions, leading to the divergence seen in the chart.
More offspring are born than can survive. Those with traits better suited to their environment are more likely to survive and reproduce. Evolution By Natural Selection Vida Chart Answer Key
In dark volcanic environments, dark mice are better camouflaged and less likely to be eaten by predators than light mice.
Below is the definitive answer key for filling out a VIDA chart. For each letter, we provide the definition, the biological mechanism, and the "magic words" that teachers look for. Traits are passed from parents to offspring through genes
Over many generations, the population of mice living on dark lava flows becomes primarily dark-furred. Summary of Evolutionary Steps Identify Variation
You would identify the specific physical or behavioral differences mentioned in the prompt. (e.g., "Some beetles are green, while others are brown.") 2. I – Inheritance I – Inheritance Variation
