In corn, the allele A allows the deposition of anthocyanin (blue) pigment in the kernels (seeds), while aa plants have yellow ke
lara31 [8.8K]

Answer:

<h2>A) Yes, 12 mu</h2><h2>B) AaWw</h2><h2>C) 0.25%</h2><h2 />

Explanation:

As given,

Allele A for  blue anthocynin.

aa for yellow kernel;

at  second locus;

W produce smooth kernel,

ww for wrinkled kernel;

Parents as given are:  AaWw and aaww

Progeny are:

blue smooth ( AaWw)= 1447;

blue wrinkle (Aaww)= 169;

yellow smooth (aaWw)= 186;

yellow wirnked (aaww)= 1510

a)

Recombinant progeny are  169+ 186= 355

non- recombinant progeny are = 1447+ 1510= 2957

so recombination frequency (RF)= 346/2957×100= 12.0054%

So a and w are linked genes.

They are 12 mu far away from each other.

b) Blue smooth parent= AaWw.

c) Aaww crossed with  aaWw

progeny are= AaWw, Aaww, aaWw, aaww,

They all are produced in same proportion =0.25% or 1/4.
