text: are there any biology wizzes out there? studied this, need help in these two questions if possible please.   a plant breeder crossed a red flowered plant with a white flowered plant and obtained all pink flowers (f1 generation). on self-pollination, these pink flowered plants produced the following offspring (f2 generation):  148 red flowered 300 pink flowered 154 white flowered  q1. in the f2 generation, the ratio of red:pink:white flowered plants is approximately: a) 1:1:1 b) 1:2:1 c) 1:3:1 d) 1:4:2  q2. if one of the pink f1 plants was crossed with its white flowered parent, the offspring would be expected to be: a) all red b) all white c) 3 pink:1 white d) 1 pink:1 white  i don't really understand ratios and how they work so thats why need help with these. i appreciate your answers, thank you! =) well we can deduce that white and red colour is dominant.  so lets say red= rr and white = rr so if you cross a rr x rr you get rr,rr,rr,rr as your f1 generation (all pink cause they are a mix) so now we cross rr x rr you will get a rr, rr, rr, and rr (meaning 1 red:2pink:1white)  now you are going to cross a rr x a rr you will now get  rr rr rr rr so you have a 2:2 ratio which can be reduced to a 1:1 ratio (or d)
