Instructions: In this lesson, we briefly discussed how cyclin-kinase complexes can malfunction due to mutations to their genetic coding. In this lab activity, you will investigate the direct effects of environmental factors on enzymes. How could things like fever, hyperthermia, changes in blood pH, or the concentration of the enzyme affect how these protein complexes function in the molecular control system of cell division

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
