In fruit flies, the gene for red eyes (R) is dominant and the gene for sepia eyes (r) is recessive. If a red-eyed heterozygous f
ly (Rr) mates with a sepia-eyed h0m0zygous fly (rr), what are the possible genotypes of their offspring? (Hint: You may want to complete a Punnett square.) Rr only
RR, Rr, and rr
Rr and rr
RR and Rr
assumeing that a punnet sqaure in use. a 2 by 2 tabel shows each combination. and combos with a dominant gene allways inherits the dominant trait with a chance to pass off to the next offspring
Knowledge of the relationship between the size (volume) of cells and their surface area helps explain the process of diffusion. Agar blocks and cells with the largest surface area to volume ratio (the smaller cubes) have the highest diffusion rates.
Some of these proteins serve to transport materials into or out of the cell. Carbohydrates are attached to some of the proteins and lipids on the outward-facing surface of the membrane. These form complexes that function to identify the cell to other cells.
