It has been proposed that the presence of black markings on the throat of kung fu geckos is coded by a dominant allele (B) and that the absence of such markings is coded by a recessive allele (b). To test this idea, heterozygous individuals are crossed (Bb x Bb) producing 500 offspring of which 350 have black markings and 150 don’t have black markings. Based on a punnett square, the expected phenotypic ratio for black markings to no black markings is 3:1.
Required:
Write down the correct statistical approach to test if the data is consistent with the expected 3:1 ratio.
