green
A = 15
B = 19
total = 34

white
A=7
B=5
total=12

b) greater number of green seedlings indicate that "green" is dominant and "white" is recessive .. both colours present indicates that the parents are heterozygous .. By the way which year and its for how many mrks??

What is this?

What is figure 1.1 about ??

as far as i can comprehend ..

1.take same species of plants
2.same amount of volume of water with dye
3.Same temperature
4.start the experiment at the same time
5.cover with plastc to avoid evaporation
6.repeat the experiment
