Hi, I just had a question about using Hardy-Weinberg. So, in a population of 200 daffodils:
YY (yellow flowers) 82
Yy (yellow flowers with white streaks) 103
yy (white flowers) 15

Calculate the allele frequencies of Y and y.
I understand that I use the equations of:
p+q=1 and p^2+2pq+q^2=1
However, I am not sure how to start this out.
I appreciate the help! Thank you in advance!

Do u know wat is d hardy weinberg hypothesis?

p2 = frequency of AA (homozygous dominant)
2pq = frequency of Aa (heterozygous)
q2 = frequency of aa (homozygous recessive)
