Assume that k and m are two unlinked genes that affect hearing. the dominant k allele is necessary for hearing, and the dominant m allele causes deafness regardless of the other genes present. what fraction of the offspring of parents with the genotypes kkmm and kkmm will most likely be deaf? ** draw the punnet sqaure and explain the answer in detail. a) 1/4b) 3/8c) 1/2d) 5/8

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
