Answer:
750
Explanation:
With the f1 generation all being red flowers we can conclude that Red is dominant (R) and white is recessive (r).
This leads to the f1 generation having Rr. If you breed two Rr together you get
1 RR
2 Rr
1 rr
75% of the f2 will have red flowers. So if you take 1000 and multiply it by .75 you will get 750
Approximately 750 flowers will be Red.
