1. In a total population of 300 adults, it was found that 200 were blondes and 100 were redheads. Upon closer examination, it was found that having red hair was the result of a recessive trait. Biochemical analysis revealed that blondes composed two genotypes: homozygous (40 individuals), and heterozygous (160 individuals). Use chi-squared analysis to determine if this population is in Hardy-Weinberg equilibrium for this gene.

The pattern of this wave changes between its beginning and end. what is true about the amplitude and wavelength of the wave when the pattern changes?

You have just sequenced a new protein found in mice and observe that sulfur-containing cysteine residues occur at regular intervals. what is the significance of this finding? it will be important to include cysteine in the diet of the mice. cysteine residues are required for the formation of α helices and β pleated sheets. cysteine residues are involved in disulfide bridges that form tertiary structure. cysteine causes bends, or angles, to occur in the tertiary structure of proteins.
