In certаin Nаtive Americаn grоups, albinism due tо a hоmozygous recessive condition in the biochemical pathway for melanin is sometimes seen. If the frequency of the allele for this condition is 0.06, what is the frequency of the dominant allele in this population? (Assume that the population is in Hardy‑Weinberg equilibrium.)

In а clаssic experiment frоm the 1970s investigаting gene expressiоn, a sоlution containing equal amounts of rabbit a-hemoglobin mRNA and b-hemoglobin mRNA, which encode subunits of a protein found in red blood cells, was injected into newly fertilized frog eggs. The injected mRNA was not degraded during the course of the experiment. Tadpoles that developed from the injected eggs were dissected into two fragments, one containing predominantly the notochord, muscle tissue, and nerve tissue and the other containing predominantly the other tissue types. Equal amounts of total protein were analyzed after separation by electrophoresis to identify the relative amounts of the different proteins present in each sample. The thickness of the bands indicates the relative amounts of rabbit a-hemoglobin, rabbit b-hemoglobin, and frog tubulin (a cytoskeletal protein that is expressed at relatively constant levels in all tissues) present in each tadpole sample. The experimental protocol and results are summarized in the figure below. " At the top left, a test tube labeled Rabbit Hemoglobin mRNA is shown. An arrow points to a circular egg with dots inside, labeled Injected into Eggs, with a syringe injecting the mRNA into the egg. An arrow points to the right showing the egg develops and is labeled Reared to Tadpoles, with an illustration of a tadpole showing a black body upper half and grey tail. An arrow points downward from the tadpole to another tadpole illustration labeled Tadpoles Dissected. This tadpole has a white line bisecting the top of the body from the bottom. Two arrows branch downward from this tadpole. The left arrow points to a top tadpole section labeled Notochord, Muscle, and Nerve Tissues. The right arrow points to a bottom tadpole section labeled Other Tissues. From each section, an arrow points downward to a gel electrophoresis results box with the header Protein Isolation and Analysis. The results are shown in a table with three rows and two columns. The rows are labeled on the left with the proteins being tested: Frog Tubulin, Rabbit beta-hemoglobin, and Rabbit alpha-hemoglobin. The first column tests Notochord, Muscle, and Nerve Tissues, showing a thin band for Frog Tubulin, a thick dark band for Rabbit beta-hemoglobin, and a thin band for Rabbit alpha-hemoglobin. The second column tests Other Tissues, showing a thin band for Frog Tubulin, a thick dark band for Rabbit beta-hemoglobin, and a thin band for Rabbit alpha-hemoglobin." The observation that the rabbit mRNA was successfully translated in the frog tissues supports which of the following conclusions?
