  2. I'm assuming that the white plant is homogenous, meaning that both genes are aa, since the white flower is a recessive gene. Since the plant is heterozygous for purple flowers results in it's genes being Aa. When you draw the punnet square, The white flower genes are on top while the other plants genes are on the side(or vice versa, it really doesn't matter). Then you complete the Punnet square. The letter of each column fills up its correspondent box below it and the letters to the rows fill up their respective box.

  4. I'm not great at explaining but if you look up how to do punnet squares(unless you already know how to do one) it could give you a better explanation.

  8. The answer is B lol just draw it ding-a-ling also........ here's the explanation my guy (if you are too lazy to draw a square and figure it out as I was {did it in my head})- basically if there is a pure dominant allele HH crossed with a pure recessive allele hh it will always all be heterozygous or Hh because if you think about it (picture a punnett square) there would be one dominant allele from the (presumably idk tho lol) father (H) crossed with the mother's recessive allele on the side of the square (h) and H+h= Hh!!!! well there you go have a nice day my little grasshoppers XD
