I'm not exactly sure of your question but here's what i think your asking, Darwin and scientists today have discovered that the ancient organisms whose remains they find look like organisms alive today because they are the living organisms' ancestors or evolved from a common ancestor. They provide valuable information about evolution and how life formed
Plicae, villi and microvilli increase the surface area for he absorption of nutrients
Answer:
Photosynthesis stems from plants, so I believe the highest level of photosynthesis would be in dense levels of greenery like maybe parks or national forests. ( sorry if its not specific enough )
Explanation:
In order for offspring to have a dominant mutation, they need at least one copy of the allele from either or both parents. So yes, at least one of the parents must have the mutated gene in order for the offspring to have the mutation.
For your second question, I'm not quite sure what you mean so I will restate two possibilities for what I think you mean:
1. The offspring does not have the mutation if none of the parents have the mutated gene: this is correct.
2. If the mutation is recessive and the child has only one copy of the mutated allele, then the child will not show the mutation. If none of the parents had the mutated gene, then it would not be possible for the child to have the mutated gene or show it.
