The abo blood type is controlled by a single locus, called i, and the human population harbors three alleles: i a, i b , and i o . each individual, of course, only carries two alleles at the locus. these alleles give rise to the blood type phenotypes, a, b, ab, and o. the relationship between genotype and phenotype is complicated. i a is dominant to i o , i b is also dominant to i o , and i a and i b are codominant, which means that the effect of both can be seen in the heterozygote.

Azoologist is studying four very closely related feline species. she wishes to compare their gestation periods. an observational study is conducted where the zoologist observes the gestation period of 50 randomly selected felines in each species. a one-way anova test is run to test the hypothesis that the average gestation period is the same for each of the four species. a level of significance of 0.05 is used, and a p-value of 0.01 is calculated. based on this result, the conclusion that can be drawn is that:
