In corn, the trait for tall plants (T) is dominant to the trait for dwarf plants (t) and the trait for colored kernels (C) is dominant to the trait for white kernels (c). In a particular cross of corn
plants, the probability of an offspring being tall is 1/2 and the probability of a kernel being
colored is 3/4. Which of the following most probably represents the parental genotypes?
TtCc x ttcc
O TTCc x ttcc
O TtCc x TtCc
O TtCc x ttcc

What are genotypes? what are phenotypes?

Why are lipids and proteins free to move laterally in membranes?

Part a - which gene to compare? in this exercise, you will use the cytochrome c oxidase i (coi) gene to investigate relationships among salmon species. (this gene encodes a protein that functions in the mitochondrial electron transport chain.) you will compare the coi gene sequences from your salmon test samples to the standard sequences for each salmon species. in order for the coi gene to be useful for distinguishing among the different salmon species, which three statements must be true?
