please answer all parts with good explanation and clear answer

Problem 1: One of the varieties of poultry has been largely built on a single-gene locus, that for "frizzled" feathers, the two alleles for this locus are known as "N" and
"F". The frizzled phenotype is produced by the heterozygous genotype NF and is highly valued by breeders. One homozygote FF produces extremely frizzled birds called
"woolies", who lose their feathers very early. The other homozygous genotype NN has normal plumage.
Consider the numbers of individuals of these varieties found in a population in the United States shown below.
Normal
650
LOND
Frizzled
750
Woolies
100
a) Please perform the appropriate statistical test to understand if this population is in Hardy Weinberg equilibrium. (please use p for frequency of the N allele and q for
that of the F allele)
Value of statistic
p value associated to the statistic is
(</>) than 0.05 (please complete with the corresponding symbol). Please use the Chi square table
provided in the slide collection for theme 3, note that the table is the same even though the test applied in theme 6 is different)
Conclusion: the population
(is/is not) in HW equilibrium
b) If the population ends up not being in equilibrium, which of the simplifying assumptions do you think are not being met and why? (What evolutionary forces do you
think are operating?)
