Suppose that goats have one gene that codes for color, where a is brown and a is white. the goats also have another gene that codes for height, where b is tall and b is short. if these two genes are unlinked, what is the probability that a cross between aa bb × aa bb parents will produce two out of six offspring that are brown and short? enter your answer as a decimal, rather than as a percentage.

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.
