Gene expression can occur at several points along the pathway from dna to rna to proteins. in one example of gene expression, the protein insulin must be trimmed to a smaller size. how is this is an example of gene expression? until the protein is trimmed, the ribosomes are not active. until the protein is trimmed, the shape of the dna blocks transcription. until the protein is trimmed, it is not useful to the cell. until the protein is trimmed, transcription is blocked by a repressor prote

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. an incomplete dominance cross is performed between a bird that is homozygous for red feathers and a bird that is homozygous for blue feathers. purple offspring result. then, two of the purple offspring are crossed. according to the punnett square for this cross, how many of the offspring from the second cross will have a feather color that results from incomplete dominance? 1 in 4 2 in 4 3 in 4 4 in 4
