I need help on these questions...
1) Two alleles, A (Melanic) and a (Typical or non-melanic), control a polymorphism in this species in which the melanic condition is geneteically dominant over the normal, light typical condition
What are the genotypes / phenotypes in this polymorphism?
2) 150 years ago a sample of 800 moths contained 722 non-melanics and 78 melanics (dominant over melanic)
Also from this information, (and assuming the Hardy-Weinberg equilibrium), calculate the corresponding melanic (A) and typical (a) allele frequencies (p and q respectively)
What are the phenotype frequencies in this sample?
Any help is much appreciated

1. There will be two phenotypes (normal/light) and three genotypes (AA, aa and Aa)
I suggest you start over and relearn this area of biology because the second question is much harder than the first which covers the basic principles, re go over the basics before you attempt to answer the second question. what stopped you getting an answer to the first question, is there anything in particular you need help on regarding geno/phenotypes?
