Explanation:
Homozygous Red, or Homozygous Dominant: RR
Yellow fruit must be homozygous recessive, or else the yellow would show: rr
Plant 1 Genotype: RR
Plant 2 Genotype: rr
The punnet square is attached.
The Genotypic ratio is: 4:0 or just Rr because the offspring turned out to be 100% heterozygous.
The Phenotypic ratio is just red, because no other colors come out of the offsping.
Hope this helps :)

The observations that supported their conclusions include; Bird wing butterflies were found throughout the Malay archipelago, but species differed slightly from island to island.
Bird families clustered geographically: cockatoos in the Malay Archipelago and Australia, macaws and hummingbirds in the America.
Mockingbirds from different Galapagos islands had Subtle, consistent differences.Tortoise from different Galapagos islands have distinct shells
The bony shells of armadillos resembled fossilized shells from the extinct Glyptodon.
The fossilized remains of giant sloths were similar to the smaller, living sloths Darwin encountered. Therefore, the resemblance between species and the variations among distant species led to both Darwin and Wallace to conclude that species change over time.
