Part A. Based on the passage above, would polymorphisms be considered a form of mutation? Yes, because there is still a change in the genetic information. No, because there is no negative effect on a person's health. Yes, because they are both common and only affect physical traits No, because they are common enough to be considered a normal variation Part B. Based on the answer to Part A, what determines if someone has a mutation? if the change in the gene sequence causes a negative impact and has no beneficial side if there is any change in the genetic sequence if the change is only significant enough to affect the well-being of an organism ifless than one percent of the population has a changed genetic sequence
Explain the process of human reproduction.
Read This! Through the process of evolution, all species have developed strategies to compensate for their sumvor ship type. Insects lay eggs by the hundreds Mammals keep thelr young close by and protected until they reach adulthood. Factors such as these allow populations of specles to survive and thrive despite their survivorship curve. 4. How do you think populations with Type II or III survivorship compensate for high pre reproductive mortality? 5. Consider the evolutionary strategies that each survivorship type has developed for producing and rearing their young Propose an explanation for why type I survivors have the highest relative number of Individuals /1000 births that survive until they reach post-reproductive age? 6. Under what circumstances might human populations not show Type I survivorship?
