Today, we know these "factors" are alleles. an allele is an alternative form of a gene that is located at a specific position on a specific chromosome. we usually have two alleles for a trait, one inherited from each parent. we can rework mendel's original crosses with the notation for the alleles for seed color. this notation is called the genotype. when the pair of alleles is identical, they are called homozygous. when the pair is different, they are called heterozygous. capital letters represent dominant traits; lower case letters represent recessive traits. dominant traits can mask recessive traits. the colors yellow and green are called the phenotype. how would we describe the genotype of the green seeds?

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.
