In addition, helmet and head cap color were assessed in guinea fowl, and earlobe color, comb type (normal, rose, and pea comb), feather distribution (normal, naked neck, ptilopody, and crested head) and feather structure (normal, frizzled, and silky feather) and polydactyly were recorded in local chickens.
Observed allele frequencies (p of dominant alleles, q of recessive alleles) were calculated for major genes in local chickens (naked neck, Na/na; frizzled feather, F/f; rosea omb, R/r, pea comb, P/p; silky feather, H/h; crested head, Cr/cr; ptilopody, Pti/pti; polydactyly, Po/po) using the Hardy-Weinberg equilibrium: q = [square root of (m/t)] and p = 1 - q, where m is the observed number of birds with the recessive phenotype under consideration andtis the total number of studied birds.
These were rose comb, ptilopody and polydactyly for female chickens, pea comb, adaptive gene combinations, crested head and polydactyly for male chickens as well as brown, light grey, sky blue and bronze for both male and female guinea fowl.
