In guinea pigs, black fur is dominant over white fur and rough fur is dominant over smooth. A cross between two guinea pigs hybrid (heterozygous) for both
traits produces some offspring that have rough black fur and some that have
smooth black fur. What fraction of the offspring have rough black fur and what
percentage have smooth black fur?

Imagine you are a student in alfred hershey and martha chase's lab in the late 1940's. you are given five test tubes with the e. coli bacteria that were infected with t2 bacteriophage that have been labeled with 32p or 35s. unfortunately, you forgot to label the tubes and are now uncertain which were 32p labeled and which were 35s labeled. you place the contents of each tube in a blender and pulse it for a few seconds to shear off the protein coats from the bacterial outer membranes. you then centrifuge the contents to seperate the protein coats and the bacterial cells. you then check for radioactivity and obtain the results shown below. which tubes contained e. coli infected with the phage labeled with 32p? select all tubes that apply.
