In four o’clock plants, red colour (R) is incompletely dominant over white (r), the heterozygous having pink colour. What will be the offspring in a cross between a red flower and a pink flower?
In the monohybrid cross, red is incompletely dominant over white. Red flowered plants have genotype RR and white-flowered plants have genotype rr. Pink flowers have a genotype Rr. Red flowering plants will form gametes with R genes and pink flowers will produce two types of gametes with R gene and r gene. Arrangement of gametes in chequerboard.
