A population of 159 elephants was assessed for a gene that affects the presence or absence of tucks. The presence of tucks is the dominant trait and the lack of tucks (or tusklessness) is the recessive trait. When this population was studied, it was observed that the number of individuals with each of the possible genotypes was as follows: Genotype TT (tusks) Tt (tusks) tt (tusklessness) Number of Individuals 72 61 26 Predict the Hardy-Weinberg genotypic frequencies. Are these frequencies in agreement with the observed numbers? Based on this result what can you conclude? (14 marks) To receive full marks you must show your work.
