Streptococcus pneumoniae is one of the leading causes of community-acquired pneumonia and is particularly problematic in older adults. One reason for its pathogenicity is its ability to avoid phagocytosis by host leukocytes. This is accomplished through the production of a that surrounds the cell.

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
