PLEASE HELP ASAP What will occur if a species is divided into two groups and allowed to reproduce in different environments for many generations?
1. divergence, potentially giving rise to two different species
2. random mutations, all of which will decrease fitness
3. divergence, but these will never be two different species
4. natural selection, keeping both groups genetically static

identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.

children tend to take more after their grandparents more than their parents. it’s the dna you received that was passed down to you somewhere in your family. maybe one of your grandparents had/has straight hair and you might have gotten it from them.
