in oak trees, acorn texture and cap color are controlled by two linked genes. smooth (s) is dominant to rough (s) acorn texture. dark cap color (b) is dominant to a light cap color (b). you cross an oak that produces smooth, dark capped acorns and is heterozygous at both loci to an oak that is true breeding for rough, light capped acorns, and observe the following f1 progeny: 27 smooth acorns with dark caps 398 smooth acorns with light caps 401 rough acorns with dark caps 24 rough acorns with light caps the phase of alleles in the heterozygous parent oak producing smooth, dark capped acorns is: question 3 options: sb / sb ss/bb sb / sb ss bb ss / bb ss / bb
