A cross between two tailless mice (phenotype) produces tailless and wildtype offspring in a ratio of 2 tailless: 1 wildtype. Matings between the tailless progeny and wildtype individuals produce a 1: 1 ratio of tailless to wildtype. What is the most likely genotype of the parental tailless mice

How does the molecular clock work? a. it analyzes the brain functionality of two different species. b. it examines and compares the physical characteristics of two different species. c. it illustrates relationships between two different species. d. it compares the number of mutations that exist in the dna of two different species.

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.
