In cattle, the allele for solid coat color is dominant (R) and the allele for white-spotted coat is recessive (r). A rancher crossed two cows, both solid color. What combination of genes in the solid-coat parents could result in offspring with the white-spotted phenotype? Choose the correct answer.

rr and rr

Rr and Rr

RR and rr

RR and RR

Rr Rr

Explanation: because both have solid color which is dominant so R should be present in both parents having Rr being crossed will result in rr for one offspring so the chance will be 1/4 or 25% that an offspring will have white spotted color
