Consider the chromosome.

The parts of a chromosome are labeled. The lines on the chromosome are labeled b.
Which best describes the function of the part labeled b?
carries all the genetic information of the organism
provides the master instructions for the cell
joins sister chromatids
codes for a specific trait

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
