For simplicity, we will assume that golden manes (G) are dominant over black manes (g), and thick manes (T) are dominant over thin (t).(In reality, the inheritance of these traits is a lot more complex and lions exhibit a range of mane colours from golden to brown to dark brown to black â but here we will keep it simple.)
Phenotype | Number of lions | |
Locus 1: Mane Colour | Golden | 821 |
Black | 211 | |
Locus 2: Mane Density | Thick | 354 |
Thin | 678 |
(i) The frequency of black manes: 0.204
(ii) The frequency of golden manes: 0.795
(i) The frequency of thick manes: 0.343
(ii) The frequency of thin manes: 0.656
Locus | Genotypes | Phenotypes |
T (Mane Thickness) | TT | Thick |
Tt | Thick | |
tt | Thin | |
G (Mane Colour) | GG | Golden |
Gg | Golden | |
gg | Black |
Assuming the African population is in Hardy-Weinberg equilibrium for the two loci, what are the observed frequencies of each allele (G, g, T and t) in this lion population?
Round your answer to three decimal places and submit your answer in the correct format (e.g. 0.062).
(a) Frequency of the G allele = ---------------------------
(b) Frequency of the g allele = ----------------------------
(c) Frequency of the T allele =----------------------------
(d) Frequency of the t allele = ----------------------
