Document Summary
Double helix phosphate, sugar (deoxyribose), base. A gene is a sequence of bases found on the dna strand. A gene is a segment of a dna strand. Each has a particular code; determined by . The number of bases in the sequence. The type of bases in the sequence. The order of the bases in the sequence. If you change the code then you change how the trait is expressed. For each pair of chromosomes you get one from your mom and one from your dad. Allele a variant from of a gene. Also have their own codes to determine traits. Genotype the base code found on the dna. Codes for the physical traits you can touch and see. Study of changes in genotype frequencies from one generation to the next. The sole origin of a brand new trait in a species. One base can be substituted for another base. Deletion occurs when a base is removed.
