In tomato plant, red ($R$) is dominant over yellow ($r$) for fruit color and purple ($P$) is dominant over green ($p$) for stem color. Fruit color and stem color assort independently. The number of progeny plants of different fruit/stem colors obtained from a mating are as follows:

Red fruit, purple stem –  $145$

Red fruit, green stem –  $184$

Yellow fruit, purple stem – $66$

Yellow fruit, green stem – $47$

What are the genotypes of the parent plants in this mating?

  1. $RrPp \times Rrpp$
  2. $RrPp \times RrPp$
  3. $RRPP \times rrpp$
  4. $RrPP \times Rrpp$
