Most vaccines protect only against pathogens that fall within a certain region of antigenic space. Suppose that a vaccine protects against any strain falling within a sphere of radius 2 centered at thepoint (2,1,0) in antigenic space. For each strain, determine whether this vaccine will be effective.(a) A strain located at (0,0,0) in antigenic space(b) A strain located at (1,0,3) in antigenic space(c) A strain located at (1,0,1) in antigenic space(d) A strain located at (1/4,2,1) in antigenic space

What is the difference between sex-linked traits and autosomal traits in humans? a. sex-linked traits can only be passed from fathers to sons, while autosomal traits can be passed on from both parents to offspring of any sex. b. sex-linked traits are passed on through the x and y chromosomes, while autosomal traits are passed on through the other 22 chromosomes. c. sex-linked traits only affect females, while autosomal traits affect both males and females. d. sex-linked traits refer to genes that are on the x and y chromosomes, while autosomal traits refer to genes on all 23 chromosomes.
