Purple flower color is dominant over white flower color in peas. suppose two white flowered pea plants are crossed and produce 1000 offspring. how many of those offspring would you expect to have white flowers?

Since purple is dominant over white, it is fair to say that white is recessive. The crossing over of two white plants suggest that the parents are both homozygous recessive. Crossing over of 2 homozygous recessive white plants would produce progeny. In the production of 1000 offspring by two white plants, all of the1000 progeny would be white as well.
