Answer:

  • A) Straight (S) is dominant and Red (R) is dominant
  • B) SsRr = Straight, red and Ssrr = Straight, streaky
  • C) Straight, red = 3/16 , Straight, streaky = 3/16 ,  Incurved, red = 1/16 ,  Incurved, streaky = 1/16

Explanation:

A) Straight (S) is dominant over incurved (s)

Red (R) is dominant over streaky (r)

B) SsRr = Straight, red

Ssrr = Straight, streaky

C)                            Sr                                          sr

SR        SSRr (straight, red)                       SsRr (straight, red)

Sr         SSrr (straight, streaky)                 Ssrr (straight, streaky)

sR        SsRr (straight, red)                       ssRr (incurved, red)

sr         Ssrr (straight, streaky)           ssrr (incurved, streaky)

Straight, red = 3/16

Straight, streaky = 3/16

Incurved, red = 1/16

Incurved, streaky = 1/16
