I believe the answer is that a dimpled chin is controlled by a single gene with multiple alleles and height is controlled by many genes. Alleles are alternative forms of a gene, and they are responsible for differences in phenotypic expression of a given trait. A gene for which at least two alleles exist is said to be polymorphic.
It allows flexible movement that is controlled. Please mark Brainliest!!!
Answer: conservative model
Explanation: DNA isolated after one generation produced a single band which was a higher and intermediate in density between the heavy and light Nitrogen isotopic DNA used, showing that the first generation was a hybrid DNA. This observation fit with the dispersive and semi-conservative models only. And so at this generation, the conservative model was discarded.
It’s A, the cell must be a eukaryotic because it has a cell membrane and a cell wall.
